How to Calculate Shear?

Shear stress is the force, f, acting on a given section divided by the cross sectional area, a, of the section, calculated in the direction of the force. E.g., for a force, f, normal to the surface of a beam having a cross sectional area of a, the shear stress is = f/a.

How to Calculate Shear?

Calculating shear is an important part of structural engineering and engineering mechanics. Shear is the force that can cause a structure to bend, twist or deform when a load is applied. Shear is typically measured in kilonewtons (kN) and is usually calculated when designing a structure to determine its strength, stiffness and stability.

To calculate shear, the load must be known, as well as the area of the structure, the distance between the points of application and the angle of inclination of the load. Shear can be calculated using the following equation:

Shear force = Load x Area x Distance x sin(angle of inclination)

For example, if the load is 40kN and the area is 0.2m2, the distance between points is 5m and the angle of inclination is 60 degrees, then the shear force can be calculated as follows:

Shear force = Load x Area x Distance x sin(angle of inclination)

Shear force = 40kN x 0.2m2 x 5m x sin(60)

Shear force = 40kN x 0.2m2 x 5m x 0.866

Shear force = 17.
