In the figure, a 22 kg block is held in place via a pulley system. The person's upper arm is vertical; the forearm makes angle 0 = 33° with the horizontal. Forearm and hand together have a mass of 2.0 kg, with a center of mass at distance d₁ = 16 cm from the contact point of the forearm bone and the upper-arm bone (humerus). The triceps muscle pulls vertically upward on the forearm at distance d₂ = 2.6 cm behind that contact point. Distance d3 is 33 cm. Take the upward direction to be positive. What are the forces on the forearm from (a) the triceps muscle and (b) the humerus? Triceps com Humerus- d₁- (a) Number Units (b) Number Units Block

To get up on the roof, a person (mass 70.0 kg) places 6.00-m aluminum ladder (mass 10.0 kg) against the house on a concrete pad with the base of ladder 2.00 m from the house. The ladder rests against a plastic rain gutter, which we can assume to frictionless. The center of ladder is 2.00 m from the bottom. The person is standing 3.00 m from the bottom. Find the normal reaction and friction forces on the ladder at its base.
In an emergency situation, a person with a broken forearm ties a strap from his hand to clip on his shoulder as in Figure P8.92.

The patellar tendon attaches to the tibia at the tibial tuberosity at a perpendicular distance of 4.91 cm from the center of the knee joint. During an isometric contraction, the lower leg is held at an angle of 35° of knee extension with a 400 N weight strapped to the ankle. The weight is 52 cm from the knee joint center. What is the force produced by the quadriceps to hold this position? Ignore the weight of the leg.
A 50 N hand and forearm are held at a 35° angle to the vertically oriented humerus. The CG of the forearm and hand is located at a distance of 12.5 cm from the joint center at the elbow, and the elbow flexor muscles attach at an average distance of 2.5 cm from the joint center. (Assume that the muscles attach at an angle of 35° to the forearm bones.) How much force must be exerted by the forearm flexors to maintain this position?
The forearm shown below is positioned at an angle with respect to the upper arm, and a 5.6 kg mass is held in the hand.
