Dan's biceps muscle has a moment arm about the elbow joint of 0.011 m when the joint is held at a joint angle of 90 degrees and can produce a force of 526 N. His forearm is 0.24 m from the elbow joint center to the center of his hand where he grips a handle. His forearm has a mass of 1.2 kg and the center of mass is located directly above the elbow joint. How much force can he deliver to the handle with force from his biceps?
Homework Answers
moment about center of mass = 0.011*526= 5.786
since system is in eqilibrium, therefore ,
5.786= (1.2*10 + x) *0.24
24.1107 = 12 + x
x =12.1107 N

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...

#1 The elbow joint is flexed using the biceps brachii muscle, which remains essentially vertical as the arm moves in the vertical plane. If this muscle is located a distance a from the pivot point A on the humerus, determine the variation of the moment capacity about A if the constant force developed by the muscle is F. Plot these results of M vs. θ for-60 < θ < 80

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...

The forearm of a person has a moment of inertia of 0.08 kgm^2 about the elbow joint. the forearm is held vertically and the bicep muscles exerts a horizontal force on the forearm at a perpendicular distance of 2.1 cm from the elbow's rotation axis. if the forearm has the resulting angular acceleration of 1.2 rad/s^2, what is the magnitude of the biceps muscle's force?
