The vertical shaft with a diameter of d = 25 mm is supported by a thrust collar that rests on a 27-mm-thick plate. The thrust collar is 19-mm thick. Assume that the load P causes a compressive stress of 100 MPa in the shaft. If the bearing stress between the thrust collar and the plate is limited to 30 MPa, determine the minimum outer diameter Dcollar that must be used for the thrust collar. Plate Thrust collar Determine the cross-sectional area of the shaft. Answer: A = i mm² Thrust collar area ● d Dcollar

System of Forces

A force is an external influence or agent that changes the state of a system. According to Newton's second law, the force applied to a body is proportional to the change in momentum of a body. Hence, whenever a force is applied to a body, its momentum changes. If the body is at rest, under the action of force, its state of rest changes to motion. In other words, the magnitude of the momentum of the body changes from zero to a measurable value. Similarly, if the body possesses some initial velocity, it has some associated momentum, the effect of force can cause the body to halt or come to rest, that is, the momentum reduces to zero.
