##### Reference no: EM13315247

You hold a 1.80 N Softball in your hand. Consider your forearm and hand to be a uniform rod with a mass of 1.65 Kg and the distance between the elbow joint and the ball in your hand is 2L=30.0 cm. Your bicep exerts an upward force of 12.5 N on the forearm and is attached at a distance of D=4.00 Cm from the elbow.

Using the elbow joint as the axis of rotation, determine the magnitude of the net torque acting about the elbow due to the forearm, hand, and ball.
