Characteristics:
Physical Properties:
Pine tree has thick and scaly bark from which a lots of branches arises. These branches are arrange in spiral manner.
Pines tree are evergreen plant. They have leaves whole the year on their bark. These leaves are needle like in shape.
Pine reproduction is carried out via cones which contain male and female sex organs.
A few pine plants also produce nuts that are used in human diet.
Pines tree are also used as decorative purpose. They are also known as Christmas trees.
Their life span depend on type of species, different species have different life span.
Mechanical Properties:
Mechanical properties refers to those properties which effect performance of wood species. Mechanical properties may include specific gravity, strength, movement and stability.
Strength tensile of Pine tree which is also a type of mechanical property is described as follows:
In static bending it is about 70-90 MPa.
In compression parallel to grain is about 40-49 MPa.
In tensions along the fibers is about 100-116 MPa.
Modules of elasticity in static bending is 8.0-13.1 GPa.

There is two type of force affecting pine tree, these are horizontal and vertical forces. This horizontal force is due to wind factor and the vertical force is due to gravity. The horizontal and vertical forces are substantiated by the total turning moment applied at any height of the stem. A tree is assumed to be fall down or break, if the total turning moment exceeds the support provided by the root soil plate anchorage. The ability of any tree is depend upon its root mass, the depth and the diameter of the root soil plate and also on properties of the soil. When a tree is displaced by the force of the wind, the weight of the root and the soil helps to hold down that tree in oppose to win velocity and thus resist the overturning of forces. In case of pine trees these two forces plays important
The tensile testing was done on the three composite specimens (90°, and two 45°) were completed with a servo-hydraulic load frame with a wedge. The one in the lab was the MTS 647 hydraulic wedge grip and an 810 material test system. The specimens had strain gages with a Wheatstone bridge to collect data such as time, distance, load, axial strain, and transverse strain. From the strain gages, evidence can support how and when the specimen material failed under the stress being applied to it. The test was run for three times on three different specimens. The first specimen that was tested in the hydraulic load was the 0°/90° specimen, which is made of carbon and epoxy laminate composite.
The leaves of the eucalyptus tree hang vertically. This is to reduce the amount of sunlight the tree is exposed to reducing transpiration.
He also uses the visual element of “Shape and Mass.” The trees are 3D representation of actual trees. They are over 40 foot tall and very heavy; therefore they consume a large amount of volume and mass. The trees appear to be constructed from geometric shapes but also try to follow the form of nature in a more organic way.
As the city’s first official landmark, residents have celebrated this Torrey Pine since its 1888 origin. Judge Thomas Ward carried home this seedling from Santa Rosa Island and planted it outside his home. Legend has it that city residents were in a friendly competition to see who could grow the most unique plant. As one of the most rare pines, Ward felt he won with this Torrey Pine. He truly did pick a winner. Crowned an official Champion in 1973, this tree rises 126 feet tall with an enormous crown spread of 130 feet.
In the novel Walk Two Moons by Sharon Creech the author uses trees throughout the story to symbolize many different things. There are different kinds of trees: maple, oak, willow and aspen. Each type of tree “had a special flavour all of its own” (pg. 80) and represents a different thing in the novel. The Sugar Maple Tree symbolizes Sal and her mother.
The Eastern White Pine is found in Georgia through the mountains and the upper Piedmont. These types of pine trees grow best in moist areas, such as near a river, or in areas that have a lot of hardwood trees as well. They can be recognized by their leaves, which look like needles and grow in bundles of five. The Eastern White Pine is known as one of the largest pines in Georgia. Historically these trees grew to be up to 175 feet tall but now in recent years only grow to about 100 feet in height. This type of pine is also a rapid grower. An Eastern White pine can reach forty feet in about twenty years, which is relatively fast for a tree.
Used navigation device to find the longitudes and latitudes to the location of the sweetgum and black oak tree. Took pictures twice a week of the trees changes over the weeks and Observation the process of leaves changes and leaves falling from the weather conditions. The data we gather will be Compare from previous data from Project
Pine trees have two subgenus, one is the Strobus and the other one is the Pinus. (Earle, Christopher J. "Pinus (pine) Description - The Gymnosperm Database) There are about 114 species of Aspen out there. (Earle, Christopher J. "Pinus (pine) Description - The Gymnosperm Database) The main four types of Pine trees are scotch pine, ponderosa pine, bristlecone pine and black pine. (Lovetoknow Corp. "Pine Trees.") Pine trees are usually taller than 250 feet and have a lot of spiky leaves. (Lovetoknow Corp. "Pine Trees.") These leaves have a long vine then small spiky thin pieces of leaves branch out of the vines. (Lovetoknow Corp. "Pine Trees.") Pine trees barks are a mixture of green and brown and are quite smooth besides the little bumps. (Lovetoknow Corp. "Pine Trees.") Pine trees also have small pine cones which grow on the tree. (Lovetoknow Corp. "Pine Trees.") They are usually brown and face downwards with spikes facing downwards. (Lovetoknow Corp. "Pine Trees.") Pine trees are usually very popular in christmas, because they are easy to plant and not as hard to nurture as other plants. (Lovetoknow Corp. "Pine Trees.") For example the Aspen trees which are very hard to keep alive. Most Pine trees can last from 100 years all the way up to 1000 years, if they are not chopped down for paper by that time that is. (Lovetoknow Corp. "Pine Trees.") Even though these trees last for quite a long time they still have diseases. Some examples are, the canker disease, needle cast, white pine blister rust, root rot and beetle infestation. (Lovetoknow Corp. "Pine Trees.") Most of these disease makes the trees crack in half. (Lovetoknow Corp. "Pine Trees.") To prevent this sort of thing, you should not over fertilize the pine tree and don't constantly water the plant. (Lovetoknow Corp. "Pine Trees.") Aspen trees and Pine trees both grow small cones, which grow on the tree after it matures or while it
The Palmetto tree, which is the South Carolina State Tree, was added because of the use it had in the defense of Sullivan's Island against an attack in 1776 during the American Revolution. British ships were not able to take down the walls of the fort which were built by Palmetto logs. The cannonballs would eventually have no effect on the fort because the soft palmetto tree would absorb the impact of the shock given by the cannonball and simply fall of. The trees were a huge factor in the winning of that
Scotch pine is native to Europe and Asia. From the British and Scandinavian peninsulas through central Europe south to the Mediterranean and east through eastern Siberia, Scotch pine can be found at varying elevations. It is adaptable to a wide variety of sites and accordingly, has been widely planted for both Christmas tree and ornamental purposes. Although plantations have been established in the United States for the purpose of producing forest products, the species does not perform as well as in its native habitat. The Scotch Pine is invasive; it’s not native to an ecosystem and which causes harm. They can harm the environment, the economy or even, human health. Scotch Pines are evergreen trees that come in many varieties. Pines need special
Based on the current conditions of the area, we hypothesis that tree survivability will be highest in elevations above 3,000 feet and below 3,300 feet, highest in slopes between 0 - 45 degrees, and highest in aspects between 0 - 33 degrees. Tree survivability will also be highest in area with the best soil, water quality, and forest health conditions for successful tree sapling growth.
The three-needled Rocky Mountain ponderosa pine (Pinus ponderosa var. scopulorum) is the prevalent form of pine throughout the Colorado Plateau. Gambel oak (Quercus gambelii) is commonly associated with the ponderosa pine at lower elevations as well as the New Mexico locust (Robina neomexicana). At higher elevations it shares habitat with southwestern white pine (Pinus strobiformis), Rocky Mountain white fir (Abies concolor var. concolor), Rocky Mountain Douglas-fir, (Pseudotsuga menziesii var. glauca), and quaking aspen (Populus tremuloides). Understory plants which are commonly found in these forests include grasses such as mountain muhly and Arizona fescue, forbs such as lupine, as well as apache plume, buckbrush, currant, and cliffrose.
The tree is a stern portrayal of strength and also reliability being firmly rooted to the ground, and consistent in its ways. The tree furthermore functions as a place of stability where the bird can rest and grow still dependent to the tree but yet independent at the same time.
If you notice any visible damage or decay on the roots, then the tree may be structurally unsound.
Plants are abundant throughout the Pine Barrens. The pine tree is the most typical, especially the pitcher pine. This is a pygmy pine tree only about ten feet. Other trees consist of pin oaks and cedar. Cedar trees and their roots are what make the water a brownish red color. One of the most popular plants is also their main crop. This plant is the blueberry and cranberry bushes. The Pinelands also have rare plants. The pitcher plant, for one is related to the Venus Fly Trap. This amazing plant traps flies by attracting them with a liquid which is like pollen located at the bottom of the pitcher.
