Gear C is rigidly attached to arm AB. If the moment couple M = 50 ft lb, determine the equivalent force and moment couple system at A. The force A2 = 30 lbs. Resultant force components Rx and Ry are positive if right or up and negative if left or down, respectively. The moment couple is positive if counterclockwise and negative if clockwise. Remember to check units. 22 in. 25° 10 in 18 lb 30⁰⁰ 16 in. A₁ lb B i+ 40° * 25 lb The equivalent force is R = The corresponding moment couple is MA = 30 xj lb. 1080 lb.in.

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.
