How to calculate the shear force of the pin

The shear force of the pin can be calculated by the formula.
Common materials for pins include carbon steel, stainless steel, 35 or 45 steel, and 35, 45, 50, T8A, T10A, etc.
Carbon steel pins have high strength and are suitable for some heavy-duty connection occasions.
Stainless steel pins have good rust resistance and are suitable for humid and corrosive environments.
35 or 45 steel is the basic material for pins, while the materials for safety pins include 35, 45, 50, T8A, T10A, etc., and the hardness after heat treatment is 30~36HRC.
The pin sleeve material can be 45, 35SiMn, 40Cr, etc., and the hardness after heat treatment is 40~50HRC.
The selection of these materials is based on different usage occasions and characteristics to ensure the performance and durability of the pins in various mechanical applications.
