A construction worker punched a bamb00 wall (the wall has a shearing strength of 241 MPa). His hand is equivalent to 0.6% of the mass of his own body, and forms a circular shape with a compressive stress limit of 0.31 mPa before it bleeds. Assumptions: Diameter of his hand= 3 inches Mass of worker= 110 pounds Find for: a. thickness in cm of the hole he made on the bamboo wall b. force he exerted to punch the wall
