**About Pin Shear Calculator (Formula)**

With the Pin Shear Calculator, you can calculate the pin shear stress and bearing area stress of pin joints, which are commonly used in mechanical engineering. They involve pins passing through holes in plates to connect them.

When the pin is bent due to the applied force, it experiences pin shear stress, whereas when the plates are bent due to pin shear stress, the plates experience bearing area stress.

**To calculate the pin shear stress, we use the formula:**

**SS=4∗AF/(pi∗D^2)**

Where SS is the pin shear stress, AF is the applied force, and D is the diameter of the pin. The pin shear stress is measured in N/mm² or lbs/in². The higher the pin shear stress, the greater the risk of failure of the joint.

**To calculate the bearing area stress, we use the formula:**

**BS=AF/(t∗d)**

Where BS is the bearing area stress, AF is the applied force, t is the thickness of the plate, and d is the diameter of the pin. The bearing area stress is also measured in N/mm² or lbs/in². The bearing area stress represents the stress on the plate material around the hole where the pin is inserted. If the bearing area stress is too high, it can lead to plate deformation, cracking or even failure.

For engineers who need to design or analyze pin joints, the Pin Shear Calculator is a useful tool. This calculator can help engineers determine the pin shear stress and bearing area stress of their joint quickly and accurately, ensuring that the design is safe and reliable.
