Introduction
Mechanical systems come in many forms. When analyzing these systems, the loads and
accompanying stresses are points of high interest. Simple calculations can be done to find the
value of these stresses. To validate the calculations, actual st

Gyroscopic action has its advantages and disadvantages. A benefit of gyroscopes is using
its force for stability systems. A con of this torque is when a car flips while in the middle of a
hard turn at high speeds. One may wonder, when riding
