Beam Deflection Experiment

In Figure 2, the lower meniscus lies below the 3 mL line and 4 minor gradations that signify 0.1 values. Estimating the uncertain digit to be 0.04 mL, the reading we record for this particular buret is 3.44 mL.

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,

The questions in this instrument are weighted a numerical value of zero to three, with three being the highest score on each question.

Distance of the nearest point of the improvements to the buffer edge and to the 12-ft. primary structure setback.

The pendulum was pulled to about 15 cm from the motion detector. In case of the mass on a spring, the mass was pulled till just a few inches away from the motion detector.

6. The instructions so simple and direct I'm pretty sure anybody who can comprehend and follow each function has a number that you follow and complete a task.

in the xy-plane is equal to the radius (R) of the beam pipe, as shown in Fig.~\ref{beampipeconversion},

Locate the force string and use the hooked end to connect the force string to the other side of the spinning mass. Guide the force string over the pulley. Suspend the mass hanger plus an additional 0.55 kg of mass, so that m= 0.6 kg. Ensure that the weight hanger does not touch the table top. This hanging mass will be referred to as the force mass from now on, and is used to set the centripetal force, Fc. The force Fc is equal to the force mass, in kg, multiplied by gravity. Calculate this value and record it onto Data Sheet C. Adjust the tension knob so that the tip of the spinning mass is directly above the

Measure the initial width, length, and thickness of the steel specimen using a Dial Caliper. Relieve pressure in Amatrol T9014 and adjust the height of the bottom platform to insert steel specimen. Insert one pin into the bottom platform to hold the steel specimen into the fixture. Slide two locking bars down the steel specimen. Adhere one locking bar to the bottom of the specimen and one at the top, lock them in place using the attached thumb screws. Insert the Linear Vernier Caliper in the top locking bar and zero out the caliper, allowing it to rest on the bottom locking bar. Compress the hydraulic cylinder until the indicator reads a force of zero. Lock the Linear Vernier Caliper in place by tightening the top thumb screw. [1] Compress

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.

Adding additional uplift capacity to the stringers while minimizing changes to the beam cross section will be essential to preventing future damage to the stringers

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

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.

5. When both the design and the measurement specifics have been determined, a test is needed to assure that they are feasible for the purposes intended. Almost certainly deficiencies requiring revisions and additional testing will be found at this stage.

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.
