Concept explainers

Types of loading

In mechanical terminology, the term load indicates that external force/weight, either constant or variable, acts on a mechanical member/structure. The weight of an object of a specific material is also an external load, and the external force that works on a structure comes under the categories of loading. The external load generates its effects as stress and strain in the structure.

Question

A uniform horizontal beam with a length of 12.00 m and a weight of 400 N is attached to a wall
by a pin connection. Its far end is supported by a cable that makes an angle of 60.0° with the
horizontal. If a 800-N person stands 4.00 m from the wall, find the tension in the cable, as well
as the magnitude and direction of the force exerted by the wall on the beam
