The drawing depicts a hand drill – if the drill bit jams when subjected to forces as shown in the drawing (values noted below) determine the absolute values of the internal shear forces acting on the cross section of the drill bit at A. Be sure to use the correct units. a = 3 in, b = 9 in, c = 6 in, d = 6 in, e = 6 in, f (handle  from center line of drill) = 9 in. R = 10 lb, Q = 50 lb, P = 30 lb
