Learning Goal: To practice Problem-Solving Strategy 8.1 Static equilibrium Part C When you lift an object by moving only your forearm, the main lifting muscle in your arm is the biceps. Suppose the mass of a forearm is 1.40 kg. If the biceps is connected to the forearm a distance dbiceps 3.00 cm from the elbow, how much force Fbicepa must the biceps exert to hold a 700 g ball at the end of the forearm at distance dball 32.0...

3) Weightlifting Weightlifting can exert extremely large forces on the human body, especially on joints and tendons. Consider the strict curl, a lift in which the lifter uses both arms to lift a barbell. The lift is done with a pivot of the elbow. The biceps muscle contracts, pulling up on the forearm through the tension in a tendon. The weight is lifted using only the forearms, with the upper arms remaining stationary. The world record for the strict curl...

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...

Part A A 75.0 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 5.75 % of a person's weight.

How much force (in N) must the biceps muscle exert when a 25.0 kg mass is held in the hand in a stationary position when the arm is 17.4° below the horizontal? Assume the mass of the forearm is 2.46 kg. Distances relative to the elbow joint are reb = 5.12 cm; recg = 16.5 cm; ren = 37.5 cm where the distances are: eb = elbow—biceps; ecg = elbow—forearm center of gravity; eh = elbow-hand. A marble column 0.890...

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.
