I need answer within 20 minutes please please with my best wishes Hussein
It is known that a vertical force of 200 lb is required to remove the nail
at C from the board. As the nail first starts moving, determine (a) the
moment about B of the force exerted on the nail, (b) the magnitude of
the force P that creates the same moment about B if a = 10°, (c) the
smallest force P that creates the same moment about B.
