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 arm on the catapult. My independant variables are the items and their different weights

be of interest to calculate the theoretical force using a derivation of equations and comparing them

b) Determine the distance, x, from the left end of the beam to the point where the rope is attached. Note: take the torque about the left end of the beam.

2: Place the triple beam balance on a flat suface with your hands (make sure the pointer is pointing at the zero mark. If not, use the adjustment knob to adjust the pointer to zero).

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

However if the load on the beam wasn’t doubled then the beam would have been able to bear the load with a safety factor of:

The beam-placing operates in two ways depending on where beams are delivered. On one condition, that beams are delivered on the ground level, lifting trolley will pick them up directly by both ends. On the other condition, that beams are delivered at abutment, by two trucks or other carriers at each side, the front trolley will pick up the front end of beams, then the front end of beams will be released from carrier; the front trolley moves forward, simultaneously with another carrier and beams, until the rear end of beams are at the same horizontal position of the rear trolley. The rear trolley will pick up the rear end of beams then, and once again the beams will be released from carrier. After the trolley getting the beams at deck level, the latter will be placed onto the bearings. To be specific on position control, trolleys move along the main girder/ main truss, and at other direction main girder/ main truss and move perpendicularly to span, and vertical position can be handle by trolley themselve by adjusting length of wires.

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

Abstract: A force table that had three weight hangers, numerous masses and pulleys attached to it, which were used to reach static equilibrium. Third angles for each of the systems were: System 1:349.8, 350.3, 350.1; system 2: 8.3, 9.1 8.8; system 3: 9.8, 10.5, 10.2; system 4: 58.3. 57.5, 58.8; system 5: 48.7, 49.1, 48.1.

During the construction, two half-spans being assembled 50 meters above ground level had a misalignment of 4.5 inches or 114mm in camber. It was suggested by John Holland & Constructions to use a kentledge to weigh down the higher section of bridge. It so happened that they had ten, eight tonne concrete blocks on site. These were placed halfway along the higher span to

where r_1 is the radius from left side of the beam and r_2 is the radius from the right side.

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.
