We determine the dimensions of the rod. Let's assume a length of 2 m (2,000 mm) and a cross-sectional area of 1 cm² (1×10⁻⁴ m²). We observed that the rod elongated by 3 mm. We calculate the strain is the rod according to the formula: ε = ΔL/L₁ = 3/2000 = 0.0015. We calculate the stress, using the stress formula:

A ss =The thread shear area. The following formula for the Tensile Stress Area of the (male) screw. This is based on ISO 898 Part 1. see calculation below.. d p = Pitch circle diameter of thread. dp = (D - 0.64952.p ) The thread shear area = A ss. When the and male threads are the same material. Ass = 0.5.

The cross-sectional area of a round shear pin is simple to compute. area = PI () * (diameter/2)^2. The computation for a screw is more complicated. Because of the screw's threads, the diameter of the screw that should be used is less obvious. The narrowest cross-section of a screw, between the threads, is called the screw's "minor diameter".
