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...
Please Provide your thought process Step by Step!!!!!!!!! Required The woman at the right is lifting a 30-lb barbell. A mechanical model of her upper body is shown below the picture. The beam is her backbone and the cable represents her back muscles (a complex set of muscles in the real back). The Earth's gravitational force on her upper body at its center of mass is 30 lb. The Earth's gravitational force on her head, aims, and the barbell is...

The main forces med and the distances from the elbow joint are shown in the figure. biceps muscle metal sphere forearm elbow joint 0.04 m 0.15 m 1 18 N weight of the sphere 0.46 m Considering the moments about the elbow joint, calculate the size of the force...
Abe knew from his anatomy class that there are three different kinds of muscle tissue in the body. He knew lifting weights would help build the skeletal muscle and that running was good for cardiac muscle health. He was surprised to find out that his blood vessels had smooth muscle, so his exercise regimen was actually benefitting all the muscle types of his body. Correctly sort each of the characteristics into the appropriate category. View Available Hint(s) Reset Help Under...
__PRESENT Problem 8 (Bicep workout) We can estimate the tension on the bicep muscle while lifting a weight with our hand. In this exercise, the lower arm pivots about the elbow (assumed fixed), while the bicep itself is attached to the lower arm 4 cm away from the elbow (see drawings below). The weight (W) has a mass of 10 kg and is assumed to be a point mass for simplicity which exerting a force on the arm. The lower...

SG SC Break exercise into two primary movement phases such as a lifting phase and lowering phase. For each exercise, determine the following for both the shoulder girdle and glenohumeral joint Din Dip Pushing up S phase (1 & 3) The actions occurring at each joint 1 (2 & 4) the agonists (prime movers) for the shoulder girdle and shoulderjoint reach phase of the movement and then list Lowering phase S.T primarily responsible for causing/controlling those movements for each phase...
