Current Attempt in Progress A man holds a 196-N ball in his hand, with the forearm horizontal (see the figure). He can support the ball in this position because of the flexor muscle force M , which is applied perpendicular to the forearm. The forearm weighs 18.8 N and has a center of gravity as indicated. Find (a) the magnitude of M and the (b) magnitude and (c) direction (as a positive angle counterclockwise from horizontal) of the force applied by the upper arm bone to the forearm at the elbow joint. Upper arm bone - Flexor muscle Elbow joint 0.0510 m. . 40.0890 m 0.330 m- (a) Number Units (b) Number Units (c) Number Units
