Question

A hand exerts a force of 25 lbs on a scale at 16 inches from the joint center at the elbow. If the triceps attach to the ulna at a 90°
angle and at a distance of 2.5 cm from the elbow joint center, and if the weight of the forearm and hand is 12 lbs with the
hand/forearm CG located 15 cm from the elbow joint center, how much force is being exerted by the triceps?

3. A person holds a 10.0 kg lead ball in his hand, a distance of 32.0 cm from the elbow joint, as shown. The biceps, attached at a distance of 2.5 cm from the elbow, exerts an upward force on the forearm. Consider the forearm and hand to be a uniform rod with a mass of 1.50 kg. Calculate the force provided by the biceps muscle in order to hold the arm horizontally as shown. Use the elbow joint as the pivot point. Biceps 32 cm 2.5 cm
A uniform plank of wood has a mass of 19.5kg and a length of 2.0m. A person holds the plank using both hands. The first hand exerts a downward force, F⃗ , at an end of the plank. The second hand exerts an upward force, F⃗ 2, at a distance of 50.0cm from the same end of the plank. What is the magnitude, in newtons, of the force F⃗ 2 What is the magnitude, in newtons, of the force F⃗ 1?
During a circus act, one performer swings upside down hanging from a trapeze holding another, also upside-down, performer by the legs. If the upward force on the lower performer is three times her weight, how much (in m) do the bones (the femurs) in her upper legs stretch? You may assume each is equivalent to a uniform rod 40.0 cm long and 1.74 cm in radius. Her mass is 65.0 kg.
A person places his hand palm downward on a scale and pushes down on the scale until it reads (8.31x10^1) N. The triceps muscle is responsible for this arm extension force. Find the force (in N) exerted by the triceps muscle. The bottom of the triceps muscle is 2.50 cm to the left of the elbow joint, and the palm is pushing at approximately 35.0 cm to the right of the elbow joint. (please ignore the number 96 shown in the scale). Give your answer with three significant figures.
