Find the mass m of the counterweight needed to balance the 1,923-kg truck on the inclineshown as shown in the figure. Treat the pulleys as solid cylinders. The value of r is 1. The massof the small pulley is M1 = 58 kg while the larger pulley is M2 = 137 kg. Ignore the mass of thepulley connected to the truck. Are the masses of the pulleys M1 and M2 needed in thecalculation (answer this question to yourself only)?e = 45°Note: final answer with zero decimal place.

We analyzed the biceps muscle example with the angle between forearm and upper arm set at 90 degree (see figure below). Find the force exerted by the biceps muscle when the angle is 150 degree and the forearm is in a downward position. (Assume that r_1 = 5.0 cm, r_2 = 12 cm, r_3 = 30 cm, m_a = 2.4kg, and m_b = 4.2 kg. Enter the magnitude.) N

The uniform seesaw shown below is balanced on a fulcrum located d1 = 3.5m from the left end. The bigger boy on the left end has a mass m1 =75 kg. The smaller boy on the right end has a mass of m2 = 55 kg and is a distance d2 = 4.5 m from the fulcrum. The mass of the board is mb. Draw all forces acting on the seesaw board showing their directions and locations. Where would you draw the weight of the board? Identify and show the direction of rotations caused by the torques provided by all forces about the fulcrum. If the seesaw is in static equilibrium, write down the two conditions of static equilibrium symbolically using the forces and distances in the figure. Solve for the mass of the board. Calculate the force of fulcrum on the board.
A rectangular bar is hinged at point O. The bar is 3.00 m long and 2.00 m wide. Find the torque resulting from the following force about an axis through point O: F1 = 1 N. Use a positive for a counterclockwise torque and a negative for a clockwise torque.
Unlike most of the other muscles in our bodies, the masseter muscle in the jaw, as illustrated in the figure, is attached relatively far from the joint, enabling very large forces to be exerted by the back teeth. This is shown in the figure below, where a person is biting down on a bullet placed between the back teeth. (FM = 200 N and r. = 3.7 cm.) M= 2.9 cm Masseter muscle гeaction (a) Using the information in the figure, calculate the magnitude of the force exerted by the teeth on the bullet. (b) Calculate magnitude of the force on the joint.
