A hole punch has a diameter of 8mm and presses onto 10 sheets of paper with force of 6.7kN. IF each sheet of paper is of thickness .2mm, find the shear stress. [HINT: Be careful in decing what area to use. Remember that a shear force acts parallel to the surface whose area is relavant.]
shear stress= F/A
can anybody help me with this question from Physics by Giambattista.
The answer is supposed to be 1.3x10^8 Pa but i can't go about figuring out how they reach the answer.
