Deformation Of Elastic Body C2 Lab Report Essay

After the analysis on the first design brought to light the zero for members, it was decided that these members should be removed. In order to combat the flex of such a simple design the decision was made to double the thickness. This design would have the same outer frame of two triangles with a height of 20 centimeters and a width of 40 centimeters. Instead of being spaced five centimeters apart the wood be bonded directly together using Gorilla Glue. Balsa wood, a very lightweight wood with properties similar to a dense foam, was used for the main supporting member. Basswood, a lightweight yet firm wood, was used for the horizontal member. The final design added a triple layer sheet of balsa wood to rear side of the truss. This balsa sheet was added for the purpose of mounting and supporting the main structure. Additionally, a five centimeter square frame of bass wood was added at the end of the boomilever to place the loading block for testing. Once this design was implemented two key issues were discovered. First, due to the properties of the bass wood and balsa wood it was obvious that the placement needed to be reversed. The bass wood should be used for the hypotenuse and the balsa wood should be used for the

A. How did the experiment in Part I demonstrate surface tension? Use your experiment observations when answering this question.

The specimen ends were not thick or had moving wedge grips to keep it secure in the holders of the servo-hydraulic load frame. The movement of the specimen in the machine causes some of the data to be an inaccuracy. Also, the transverse strain causes issues with the strain gages that are called transverse sensitivity. The transverse sensitivity affects the accuracy of the data that is being collected for the transverse strain more than the longitudinal strain. This is greatly seen in the percent difference in the strain values such as in one case the Longitudinal strain was .4% while the transverse strain was 30%. Another issue with the strain gages was that if the strain gages weren’t properly placed on the specimen the data accuracy would

This section start from joints 4 to 8. For joints 4,6,7,8, they are with the dip of angle of 75-90, and

In the fourth stage of this experiment, the density of a gas was determined. A 250ml flask was weighed with an empty rubber balloon and the mass was recorded.

The tension in the suspenders transfers to the cables which run horizontally between the two far-flung anchorages, through which the tensional forces pass in to the ground and are dissipated. (Bagga 2014).

Egg Drop Lab Essay Forces are around us all. They are everywhere you go. In this essay I will be talking about forces, motion, and energy and how they applied to our egg drop lab. For my hypothesis”If the egg as soft stuff on the outside of our container,then the soft stuff will absorbs the pressure and force that it goes through when it hits the floor. ”This essay will have multiple details on how the forces, motions, and energies were applied to our egg lab.

If the students test how far the the stretching ability of the different type of plastics can go (dry-cleaning bag, kitchen wrap, sandwich bag, grocery bag) and you added the weights in order for the plastics to be stretched, then the plastics will stretch longer than there original size.

Observe each substance in the tube and record the physical state whether solid, liquid or gas.

As a result of trail and error method we find the angle for the third pulley and the mass that should had be suspended from it. This will balance the forces deployed on the strings due to the other two masses. While the third force is defined as the equilibrant (������⃗������) Since it is the force that establishes the equilibrium. It is also the negative of the resultant -������⃗������ = ������⃗������ = ������⃗ ������ + ������⃗������. We gathered and recorded the mass and the angle required for the third pulley to enable to put the system into the equilibrium in table 1.

Work-related interventions are a central part of occupational therapy practice and occupational therapists recognize the importance of healthy engagement within the workplace (American Occupational Therapy Association [AOTA], 2014; Wilcock & Townsend as cited in AOTA, 2014). Occupational therapists possess skills necessary to assess individuals engaged in work activities and recognize potential dangers related to poor body mechanics (Opp, 2016). Opp (2016) acknowledged a recent increase in employers taking a proactive approach in preventing work-related injuries and incorporating occupational therapists as means to evaluate the work environment and make practical recommendations to reduce the risk of workplace injury (Opp, 2016). Body Mechanics for Technicians and Mechanics will address the risk of injury, related to poor body mechanics, of technicians and mechanics working within an automotive dealership shop by offering education and training focused on proper body mechanics.

Superstructure bears the load that is being passed over the bridge and it transmits the forces caused by the same to substructure. Load received from the decking is transferred on to the substructure by Bearings. They also distribute the load evenly over the substructure material as it may not have sufficient strength to bear the superstructure load directly. Piers and Abutments are the vertical substructures which transfer the load to the earth in the foundation. Wing walls and returns are constructed as the extension of

Below are two tables in which I have recorded the data which I obtained during the experiment. The first table reflects the Relationship between the deflection/flexion of the cantilever and the mass of the load and the second table reflects the relationship between the flexion of the cantilever and the length of the cantilever.

If the load is applied at the mid- length a=b=L/2 then mid span deflection is:

3) In this experiment, only the forces on the plane surface were considered. Do the hydrostatic forces on the curved surface of the quarter-circle block affect the measurement? State why or why
