Bending Moment and Shearing 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,

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

A simple arch bridge reaches across the river in an arching shape rather than straight across the river. Gravity, the weight of the bridge and all the weight creates a downwards force. But since the bridge is curved the force becomes a downwards outward force. Rather than

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

The programmed algorithm is shown in Figure 6.The program was developed using LabVIEW System design software. The entire experimental set-up is shown in Figure 7.

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.

Also as there is no bending, this can be assumed to be equal to {ε}.

Notice in Figures 9 and 10 the comparisons in the before calculated force compared to that of the

The purpose of this lab is to calibrate two force sensors properly. Observe the directional relationship between force pairs. Observe the time variation of force pairs. We need to explain Newton’s third law in simple language.

In this experiment,we applied Newton`s first law of motion. It descripes the external force as the sum of all external force applied to the object, which equals zero in equilirbium. As we have seen in the experiment, to reach equilibrium all the forces applied on an object shoud cancel each other out and total force reaches zero.Using different forces and weights we were able to reach equilibruim ineach trial of this

This report has been written to describe an experiment performed on a channel section examining the stiffness of the beam through two differing types of deformation – curvature and deflection. The aim of the experiment was to determine the value of the flexural rigidity (EI) in two different ways; using the curvature, k, and the mid-span deflection. The testing method used for the experiment is described. The experiment found that the EI values calculated were as follows: - EIcurv = 1.76E+10 Mpa.mm4 when calculated using the curvature, k. - EIdefl

Many outside forces may bend a solid out of its original shape. The ability of a solid to return to its original form after

The forces that are involve with the experiments are basically focused on the concurrent forces. The experiment also allows us to develop the condition of balancing or arranging the angles both sides on a force table. This laboratory experiment allows us to take the mathematical abstraction of a vector to make it tangible as possible. This experiment will look into two ways 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.

Where P is the applied force, L is the length of beam, E is the modulus of elasticity of aluminum, and I is the moment of Inertia.
