__Punching Force Formula:__

The concept of Punching Force (PF) is crucial in evaluating the impact force exerted by a mechanical press or a similar device when punching a hole through a material.

The punching force, PF_{(N)} in Newton in calculated by the product of perimeter of the punch, P_{(m)} in metres, thickness of the punch, T_{(m)} in metres and shear strength of the material, SS_{(Pa)} in Pascals.

Punching force, PF_{(N)} = P_{(m)} * T_{(m)} * SS_{(Pa)}

PF_{(N)} = punching force in Newton, N.

P_{(m)} = perimeter of the punch in metre, m.

T_{(m)} = thickness of the punch in metre, m.

SS_{(Pa)} = shear strength in Pascals, Pa.

- Suppose you need to punch a hole with a diameter of 0.01 metres in a steel plate that is 0.003 metres thick. The shear strength of the steel is 350 MPa (350,000,000 Pa). Find the punching force.

Given: T_{(m)} = 0.003m, SS_{(Pa)} = 350Mpa.

Diameter of the punch, d = 0.01m , Perimeter, P_{(m)} = pi * d = 3.14 * 0.01

Punching force, PF_{(N)} = P_{(m)} * T_{(m)} * SS_{(Pa)}

PF_{(N)} = 3.14 * 0.01 * 0.003 * 350,000,000

PF_{(N)} = 32, 986N.

- Calculate the shear strength of a material if the punching force required to punch through it is 5000 N, using a punch with a perimeter of 0.05 metres on material that is 0.002 metres thick.

Given: T_{(m)} = 0.002m, P_{(m) }= 0.05m, PF_{(N)} = 5000N.

Punching force, PF_{(N)} = P_{(m)} * T_{(m)} * SS_{(Pa)}

SS_{(Pa)} = PF_{(N)} / P_{(m)} * T_{(m)}

SS_{(Pa)} = 5000 / 0.05 * 0.002

SS_{(Pa)} = 50,000,000Pa.
