Conceptual Questions Read Ch. 1 in text and answer the following questions. 1. What is this class about? Why is it important in an engineering education? Static concerns itself on how rigid bodies perform its function while forces and force systems are acting on it. 2. What is a rigid body? Why is this an important assumption in Statics? A rigid body is a solid body that can be parts of a structure or machine that are perfectly rigid and do not deform, even under large forces
