Question 2: (recommended time-50 minutes) Beam AE is supported by a hinge at point 4 and a roller at point E. A concentrated force of 20 N and a couple moment of 150 N.m act at point B. A rectangular distributed load also acts on segment CE of the beam. Determine the shear force and bending moment at the points where the loading regime changes as well as point D. Draw the shear force and bending moment diagrams. Neglect the weight of the beam. 120 N Answer: 150 N.m, B 10m 10m. 2N/m 12 m- 20 m E a) Determine the support reactions at points A and E using the FBD of the entire beam. b) How many segments are required to draw the shear and bending moment diagrams for the given beam?

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.
