What is a Shear Force?

· Shearing forces are unaligned forces pushing one part of a body in one direction, and another part of the body in the opposite direction. When the forces are aligned into each other, they are called compression forces. For example, a force of 10 newtons (N) is exerted at the edge of a beam. This is an external force.

Shear forces are best applied to relatively soft materials, again including fibrous foods. All three types of force are generated in most types of mill, but generally one predominates. For example, in most roller mills compression is the dominant force, impact forces feature strongly in hammer mills and shear forces are dominant in disc attrition

Calculating Shear Force Diagrams | SkyCiv Engineering

· What is a Shear Force? Firstly, what is a shear force? A shearing force occurs when a perpendicular force is applied to static material (in this case a beam). Think of a knife cutting through a carrot. Imagine the beam is the carrot and a point load is a knife. As the knife applies a downward force, it cuts (or shears) the carrot.
