The bones of the forearm (radius and ulna) are hinged to the humerus at the elbow....
The bones of the forearm (radius and ulna) are hinged to the humerus at the elbow. The biceps muscle connects to the bones of the forearm about 2.15 cm beyond the joint. Assume the forearm has a mass of 2.25 kg and a length of 0.425 m. When the humerus and the biceps are nearly vertical and the forearm is horizontal, if a person wishes to hold an object of mass 6.15 kg so that her forearm remains motionless, what...

The bones of the forearm (radius and ulna) are hinged to the humerus at the elbow. The biceps muscle connects to the bones of the forearm about 2.152.15 cm beyond the joint. Assume the forearm has a mass of 2.252.25 kg and a length of 0.4250.425 m. When the humerus and the biceps are nearly vertical and the forearm is horizontal, if a person wishes to hold an object of mass 7.357.35 kg so that her forearm remains motionless, what...

Example 8.6 A Weighted Forearm Goal Apply the equilibrium conditions to the human body. Humerus Biceps Problem AW = 51.5 N (12 lb) weight is held in a person's hand with the forearm horizontal, as in Figure 8.11. The biceps muscle is attached d = 0.0296 m from the joint, and the I- weight is I = 0.346 m from the joint. (b) Find the upward force F exerted by Figure 8.11 (a) A weight held with the the biceps...

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...

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. 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...

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 = 3.50 cm from the elbow, how much force Fbiceps must the biceps exert to hold a 850 g ball at the end of the forearm at distance dball = 33.0 cmfrom the elbow, with the forearm parallel to the...

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...
