· Consider an example of using a pair of scissors ("shears") to cut a piece of metal,
· Consider the simple example given below,
· By convention we will always define tension as a positive stress, and compression as a negative stress.
· Single Shear - These calculations are commonly used when examining rivets and bolts. Consider the example below with the bolt in single shear.
· Double Shear - Now consider a bolt that is exposed to double shear. Below we can see a section view of a pin through two members.
· Bearing Stress - We may also consider how the force on a pin effects the surrounding material. In the figure below we are finding the bearing stress. In this case the bearing stress will be a normal stress.
· The bearing stress as shown only needs to be considered when the member is in tension.
