Friction can be both an asset and a liability in engineering. The authors cover the laws of dry friction, screw jacks, wedge friction, and belt drives. This section helps students design systems that either minimize energy loss or maximize gripping power. Finding the PDF and Solution Works Online
One of the most valuable aspects of Hannah and Hillier's approach is their treatment of the . This principle states that the net work done by external forces on a rigid body is equal to the change in its kinetic energy.
