Lab Report : Shear Force And Bending Force

The goal of the beam project is to design and construct a beam that can hold a given amount of weight without breaking. The beam is required to hold a concentrated load of 375 lbf on the X-axis and 150 lbf on the Y-axis. The maximum allowable weight of the beam is 250 grams. The maximum allowable deflection for the beam is 0.230 in. and 0.200 in. for the X and Y-axis respectively. The beam is required to be 24 in. in length, and it will be tested on a simply supported configuration spanning 21 in. All calculations are to be done under the assumption that the density of basswood is 28 lbm/ft3 and the modulus of elasticity for basswood is 1.46x106 lbm/in2. Given the constraints of a spending cost of $10.50, a maximum beam weight of 250 grams,

Students in an AP Physics lab perform an electrostatics experiment involving two charged spheres suspended

Where τ (N.m) is torque, F (N) is the acting force on the system, θ is the angle in which the force acts on the object, and l (m) is the distance of the acting force from the fulcrum. This shows that a larger force will cause a greater rotation than a smaller force does. However, the angle of the force is also important, and if

Will surface tension be different when water is mixed with salt or detergent? I chose this experiment because I wanted to learn what surface tension is and if salt and detergent would change the surface tension of water. Also, I wanted to know why water doesn't overflow immediately after it goes over the top of a container. My independent variable is the chemical that was in the water. How many drops of water on the penny was my dependent variable. My hypothesis is, if salt water is used to test surface tension, then it will have a stronger surface tension than regular water or with detergent, as measured by the number of drops on the penny.

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

Introduction During this lab you will become more familiar with the concepts of torque. The purpose of this lab is to determine if the rotational equilibrium condition, Στ = 0, holds experimentally. Equipment Meter stick (1) - no metal ends Fulcrum (1) Clamps (4) Weight Hanger (1) Mass Set (1) Digital Scale (1)

Chemical equilibrium is a dynamic state where the rate of the reverse reaction is equal to the rate of the forward reaction. The chemical reaction is still occurring however the rate of reverse reaction is matching the rate of forward reaction hence the concentration of reactants (〖Hb〗_((aq) ) + O_(2 (g))) and products (HbO_2) no longer change, resulting in an equilibrium. (b) Which direction will equilibrium shift if the O_(2 ) concentration is increased?

Each separate truss (of the dimensions 920x5x50mm) consisted of a Pratt truss with nine diagonal members on each side of the centre. The model was tested in sufficiently isolated condition by tutors. It successfully passed the initial weight test, and satisfactorily resisted horizontal forces. Once fitted onto the testing rig, loads were applied and increased incrementally. Slight deformation was observed before failing at 12.5 kg, at which force a collection of members failed in succession, concluding the test.

Table 1 we see that the numbers are relatively the same, because the law of conservation momentum principle the total momentum before the collision equals the total momentum after and we see this in the data.

Overall, there were little to no complications for this experiment. There were modifications made to the first part of this lab, the student written portion. One change was the distances. In the original written procedure, see Attachment 02 of this report, the distances for all parts were noted as; next to the heat source, 5 inches away, and 10 inches away. After testing these measurements in the lab, the distances were alter to be next to, 2 inches away, and 5 inches away. This was done in order to produce more prominent temperature results. The distances for the 10 precision measurements were also modified. Originally the student was to take measurements for 80 seconds, starting at 2 inches away from the heat

The main objective of this lab was to measure the friction force it takes to start moving a weighted block across a table, and as it continued to move. This force was tested experimentally in three separate ways. The force was then solved graphically and mathematically through six different runs per method. TALK ABOUT RESULTS HERE.

This report aims to describe the experiment performed to investigate the stiffness of a channel section, and in particular calculate the flexural rigidity (EI) of the beam by two different sets of calculations based on the results gained in the experiment. The EI of an object is used

Purpose: The purpose of this Physics Lab is to investigate what factors determine the amount of flexion of the cantilever. Hence, the objective is to establish a relationship between the length of a cantilever, which may give some insight into the physics of cantilevers.

The beam was loaded the mid-length in 2.745 lbs. increments up to 6.745 lbs. The change in clearance of every load step was measured and data was recorded.
