Beam Deflection Lab Report
When loads are applied to a beam their originally straight axes become curved. Displacements from the initial axes are called bending or flexural deflections. The amount of flexural deflection in a beam is related to the beams area moment of inertia (l), the single applied concentrated load (P), length of the beam (L), the modulus of elasticity (E), and the position of the applied load on the beam. The amount of deflection due to a single concentrated load P, is…...

The results we obtained show that on average, we calculated a sin i over sin R to be 1.34 units. Also we can say that as the angle of incidence increased, the angle of refraction tended to increase proportionally. As the sin of i increased, the sin of R also increased. Below you can see the exact relationship between the sin of the incidence angle (i) versus the sin of the refracted angle (R). To find the slope of the…...

Rubber Band Hypothesis
The aim of this experiment is to find how the amount of stretching, when shooting a rubber band, affects the length of the shot. Hypothesis When you stretch an elastic rubber band, you store potential elastic energy inside it. When the rubber band is released, the potential elastic energy will be transformed into the same amount of kinetic energy. This will cause the rubber band to move, and the more kinetic energy we have, the longer the rubber band will…...
