The pendulum consists of a slender 2-kg rod AB and 5-kg disk. It is released from rest without rotating. When it falls 0.3 m, the end A strikes the hook S, which provides a permanent connection. Determine the angular velocity of the pendulum after it has rotated 90. Treat the pendulums weight during impact as a nonimpulsive force.
Introduction (Part 1) What is mechanics The science that describes and predicts the conditions of rest or motion of bodies under the action of forces. What happens to this body o Does it move (Dynamic) o Does it stay still (Static) o Does it deform/ deflect Mechanics is Comprised of Multiple Topics Rigid bodies o Statics o Dynamics Deformable bodies o Mechanics of materials Fluids o Incompressible o Compressible We Will Focus on Rigid Bodies Statics deals with bodies at rest. Dynamics deals with bodies in motion. Mechanics is the Foundation for Mechanical Engineering. Introduction (Part 2) Fundamental Concepts and Pri
