Compute the support reactions of the given beam below. Also, determine the maximum value of the positive and negative shear as well as the moment. Note: pt. a is hinge support, pt. b is roller support, pt. c is internal hinge support, pt. d is internal roller support, pt. e is roller support, and pt. f is a hinge support. Hint: Try to expose the internal reaction/s of the internal hinge support at pt. c as well as for pt. d internal roller support. For the units, the forces are in kN, then for the distances, take it as meters.

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.
