Two people carry a heavy electric motor by placing it on a light board 2.10 mm long. One person lifts at one end with a force of 450 NN, and the other lifts the opposite end with a force of 570 NN. What is the weight of the motor? Express your answer in newtons. Where along the board is its center of gravity located? Express your answer in meters. Suppose the board is not light but weighs 190 NN, with its center of gravity at its center, and the two people each exert the same forces as before. What is the weight of the motor in this case? Express your answer in newtons. Where is its center of gravity located? Express your answer in meters.
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.

In an emergency situation, a person with a broken forearm ties a strap from his hand to clip on his shoulder as in the figure below. His 1.60-kg forearm remains in a horizontal position and the strap makes an angle of ? = 47.0° with the horizontal. Assume the forearm is uniform, has a length of ℓ = 0.332 m, assume the biceps muscle is relaxed, and ignore the mass and length of the hand. A person with a broken left forearm faces out of the page. His left forearm is approximately horizontal, and a strap extends from a clip on his right shoulder to a position on his left arm that is a distance ℓ from the elbow. The strap is at an angle ? above the forearm. A force vector R acts up and to the right on the left forearm at a location just left of the elbow. (a) Find the tension in the strap. N(b) Find the components of the reaction force exerted by the humerus on the forearm. (Assume the positive x-direction is to the right and the positive y-direction is upward.) Rx = N Ry= N
