Shear Force Example (Intermediate - Hard)

This example for Shear Force and Bending Moments is going to be a lot more complex than the previous with the addition of calculating the Maximum Bending Moment. This is all fitted on a single piece of paper so the working out can be a lot less than shown.

Equilibrium Exam Examples

1) In using the pliers shown in Figure 1 below, 150 N forces are applied to each of the handles.

Equilibrium (Theory)

Equilibrium is the sole reason behind the static unit, Equilibrium is the forces that make an equal and opposite reaction to keep the beam, wall, arm etc where is is without moving. It is extremely important to get an understanding of "Free Body Diagrams" and also to understand which element you want to focus on within the object.

Shear Force Example (Beginner)

As discussed in the previous post, Shear Force is one of the simplest yet strangely difficult topics to learn and get your head around. But with a few examples you should be able to go into an exam and get 100% on this type of question.
The best thing about this type of question is that the end answer has to be zero making the beam in equilibrium. Therefore you always know if you have succeeded and got the physics and mathematics right.
