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.

Problem 4.128 Two systems of forces act on the beam. Are they equivalent? Strategy: Check the two conditions for equivalence. The sums of the forces must be equal, and the sums of the moments about an arbitrary point must be equal. System 1 100 N SO N Im Ans. Yes System 2 50N Solution: The strategy is to check the two conditions for equiv- alence: (a) the sums of the forces must be equal and (b) the sums of the moments about an arbitrary point must be equal. The sums of the forces of the two systems: EFx 0, (both systems) and System 1 100 N = -100 +50 =-50 (N) 50 N =-50 (N). The sums of the forces are equal. The sums of the moments about the left end are: y System 2 50 N M1 = -(1)(100) = -100k (N-m) C.W %3D 2 m M2 =-(2)(50) =-100k (N-m). C.W Thus the sums of the moments about any point on the beam are equal for the two sets of forces; the systems are equivalent. Yes
