The screw in the illustration is subjected to a 1OKN force represented by the red arrows. If the screw passes through a 40-mm diameter hole, determine the minimum required diameter of the screw body and the minimum screw head thickness needed to the screw to support the 20-kN load. The allowable normal stress for the screw is Oallow = 70(10^6) pa, and the allowable shear stress for the screw head is Tallow = 30(10^6) Pa. Projected Screw Head Diameter = 40mm Screw Diameter 10kN 10kN
