Biceps For those of you who wonder, "Why do biology majors have to do all this junk?" You hold a 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 1.85 kg and the distance between the elbow joint and the ball in your hand is 2L = 24.4 cm. Your biceps exerts an upward force of 11.3 N on the forearm and is attached at...

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 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.

1. Remember: When you lift your arm above your head, the scapula protracts, elevates, and upwardly rotates. When you bring your arm down to your side, the scapula retracts, depresses, and downwardly rotates. 2. What is the difference between the actions of the pectoralis minor and the serratus anterior? Which muscle likely contracts more when you lift your arm above your head? 3. List all the actions of the trapezius muscle on the neck. List all the actions of the...

Imagine that you are holding a 20 pound weight in a "curling" position, with your upper arm vertical and your forearm horizontal. The main muscle holding your forearm in place is your biceps muscle. By looking at your arm and considering torques around your elbow joint, which of the following is your best guess for the tension in your biceps? a) 2lbs b)10lbs c)20lbs d)40lbs e)200 lbs

So lost!!!!! Help! Problem: Assume that a 1.00 kg ball is thrown solely by the action of the forearm, which rotates about the elbow joint under the action of the triceps muscle, as shown in the figure. the ball is accelerated uniformly from rest to 10.0 m/s in .350 s, at which point it is released. The distance from the elbow to the ball is 31 cm. there is 2.5 cm between triceps muscle and axis of rotation(at elbow). A)...
