Shear force in strength of materials refers to the internal force that acts parallel to the cross-section of a structural element, such as a beam, and tends to cause deformation by sliding one part of the element past another, The shear force at the location of the point load can be calculated using the formula:
where:
- = Shear force at the point load location (in newtons, N)
- = Applied point load (in newtons, N)
