for a force P 27 kN acts on a round bar with d 50 mm the stress is P P 27 kN C CCC CCCCCC 13 8 MPa A d2 4 50 mm 2 4 The equation quot P A to be valid only for the stress must be uniformly distributed over the cross section of the bar this condition is realized if the axial force P acts through the centroid of the cross section the uniform stress condition exists
The cross sectional area of a round shear pin is simple to compute area PI diameter 2 2 The computation for a screw is more complicated Because of the screw s threads the diameter of the screw that should be used is less obvious The narrowest cross section of a screw between the threads is called the screw s quot minor diameter quot The cross sectional area at this
