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

The overhead electric hoist C rides along a track on the horizontal beam AB. In addition to the 500-KN vertical force carried by the hoist, the beam also supports the three vertical forces shown. (a) If x=5m determine the resultant of the four forces carried by the beam. (b) Determine the distance x for which the resultant of the four forces would act at the center of the span AB.
