Consider a person holding a bag like in the diagram, palm facing
upwards, forearm parallel to the floor, and upper arm making a
right angle with their forearm. Masses are added to the bag until
the subject can no longer comfortably keep the angle between their
upper arm and forearm at 90 degrees.

2. Bill is holding a 12 kg barbell in his hand. His upper arm is perpendicular to the ground, and his elbow is flexed to produce a 40º angle at the elbow joint. His forearm has a mass of 12 kg. The distance from the elbow joint to the weight in his hand is 35 cm. The center of mass (COM) of his forearm is located 14 cm from the elbow joint. Draw a free body diagram of this scenario....

The diagram above shows a side view of a person’s arm. The
forearm and hand together weigh 19N (WFH = 19N). The
center of gravity at point T is located 24cm from
the elbow joint. The person is holding a bowling ball 38cm from the
elbow and the ball weighs 47N (WB = 47N).
(a) Calculate the torque produced by the weight of the forearm
and hand about the elbow joint. Include the direction of the
torque.
(b) Calculate the...

Constants A 71.0 kg weight lifter is doing arm raises using a 7.50 kg weight in her hand. Her arm pivots around the elbow joint, starting 40.0 below the horizontal. (See the figure(Figure 1).) Biometric measurements have shown that both forearms and the hands together account for 6.40 % of a person's weight. Since the upper arm is held vertically, the biceps muscle always acts vertically and is attached to the bones of the forearm 5.50 cm from the elbow...

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...

You hold 1.80 N softball in your hand as shown in the figure. Consider your forearm and hand to be a uniform rod with a mass of 1.25 kg and the distance between the elbow on t and the ball in your hand is 2L # 24.0 cm. Your biceps exerts an upward force of 14.0 N on the forearm and is attached at a distance of d :* 2.20 cm from the elbow. Baceps Mg...

A standard man holds the upper arm vertical and the lower arm horizontal with an object of mass M = 5 kg resting on the hand, as illustrated in the figure. The mass of the lower arm and hand is one-half the mass of the entire arm. As shown in the figure, there are four forces acting on the lower arm: the force Fexerted by the bones and ligaments of the upper arm at the elbow (fulcrum), the tension T...
