A man holds a 194-N ball in his hand, with the forearm horizontal (see the figure)....
A man holds a 194-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 18.5 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...
A man holds a 183-N ball in his hand, with the forearm horizontal (see the figure)....
A man holds a 183-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 Mn, which is applied perpendicular to the forearm. The forearm weighs 20.3 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...

A man holds a 195-N ball in his hand, with the forearm horizontal (see the figure)....
A man holds a 195-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 , which is applied perpendicular to the forearm. The forearm weighs 24.6 N and has a center of gravity as indicated. Find (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

A person with their upper arm vertical and their forearm horizontal holds a 4.5-kg iron cannon ball as shown in the figure below. Assume the mass of the forearm and hand is 1.5 kg, with a center of mass 15 cm from the elbow. The center of the cannonball is 32 cm from the elbow, and the force of the biceps is applied 5.0 cm from the elbow. What force is exerted by the bicep? Elbow contact point 4.5 kg...

An athlete is measuring the force by their flexor muscle by pulling a rope horizontally at a constant force. While pulling the rope the muscle applies a force on the forearm an angle of 71° as shown in the diagram. While keeping your forearm completely vertical, the tension in the rope is at 185N. The athlete's muscle is attached to the forearm 5 cm from the elbow joint and that the weight of your forearm is 22 N with a...
