Abstract
The purpose of this lab was to determine the effects of an elastic and inelastic collision
using a ballistic pendulum. We used a plastic ball, and steel ball to conduct the
experiment. We first focused on the maxi

Abstract
In many structural designs loads applied to a body go beyond simple normal and
shear forces. Another key force that needs to be understood and accounted for is
torque.

Elasticity is a material property that plays a key role in collisions by determining
how much of the energy present in the system will be conserved. This lab analyzed how

A C-clamp is a clamping device commonly utilized in trades such as carpentry, welding, and
others. The tool can be utilized in various ways whether its holding two pieces of wood together while
an adhesive sets, or securing a material to cut or weld. The

Truss structure is a very common arrangement in the engineering field and it is a very stable structure
which cost less material to provide large support. Truss structure is usually divided in three parts,
which are top chord, web member, and bottom chord

Experimental Procedure
We were supplied with the following items for our experiment: the torsion apparatus (on
which the experiment would be conducted), a number of different sized weights (when
added together with the load body [100g], totaled 2500 grams

Data and Analysis
Our group conducted 3 different tests in order to better understand the relationship between
centripetal force, Fc, mass, radius and the velocity of an object in a situation involving circular motion.
The equation for this relationship i

The purpose of our experiment was to determine the individual loads experienced
in 5 different members of the Warren Truss after 200-gram (1.96N) loads were placed on
the 5 brackets that held the completed bridge together. These pairs of brackets

Due to the fact our group did not actively participate in the experiment and were
merely spectators, we were given an incomplete spreadsheet of the results of the
