Concept explainers

Strain energy

The term strain indicates the variation in an object's length, area, and volume when the object is subjected to an external force. The external force may be of normal, shear, moment, torque, etc. The strain in an object depends on the types of external force and cross-section of the object. Mathematically, the evaluation of strain can be obtained with the help of elastic constants.

One end of a uniform 2.60m rod with a mass of 38.0kg is supported by a cable connecting one end to the wall so that the cable makes an angle of 42.0° with respect to the rod. The other end rests against the vertical wall, where it is held in place by friction so that the rod is perfectly horizontal. A sign with an unknown mass is hung from the rod 1.90m from the wall so that wall exerts a normal force of 1790N on the rod in the positive x-direction. What is the mass of the sign in kilograms?

A machine part has the shape of a solid uniform sphere of mass 220 gg and diameter 3.50 cmcm . It is spinning about a frictionless axle through its center, but at a point at the top of the sphere, it is scraping against metal, resulting in a friction force of 0.0200 NN at that point. Find the angular acceleration of the sphere, including the direction (a positive value would indicate the +z direction and a negative value would indicate the -z direction).
