Problem 16.3 Consider the pulley-mass system shown in the figure. The diameters of the large and small pulley are D = 1.5 ft and d = 9 in, respectively. Both pulleys turn together around the same axle, Point P. (a) If the pulleys are locked by a brake and cannot turn, the weight of each block produces a moment about Point P. Determine the net moment about Point P due to the stationary blocks, in lbf-ft. (b) If the pulleys turn together at the rate of 2.0 radians per second in the direction shown, i.e. w = 2.0 rad/s in the direction shown, each of the blocks has angular momentum and linear momentum.

Problem 2: A car is pushing a barrel to the right. The pushing force P is applied by the front bumper which is level with the center G of the barrel (see figure). The barrel has mass m, radius R, and radius of gyration kG. The coefficients of static and kinetic friction between the bumper and the barrel are µs and µk. The coefficients of static and kinetic friction between the barrel and the road are also µs and µk. 1) If the barrel doesn't slip on the road, find the acceleration of the barrel and the minimum value of us required to ensure no slipping. 2) If the barrel slips on the road, find the acceleration of G and the angular acceleration of the barrel.

A homogeneous cylindrical wooden beam, with diameter of 48 cm, length of 3 m and mass of 100 kg, is hung horizontally by means of two 2 m ropes, as shown in the figure. The beam is released from rest in the position where each rope makes an angle of 60° with the horizontal. Determine the tension and angular acceleration of each rope at the exact moment the beam is released from rest. Please answer it only right someone give me incorrect answer. Answer is 2.45 rad/s^2.

A stationary bicycle wheel of radius 0.7 m is mounted in the vertical plane (see figure below). The axle is held up by supports that are not shown, and the wheel is free to rotate on the nearly frictionless axle. The wheel has mass 4.3 kg, all concentrated in the rim (the spokes have negligible mass). A lump of clay with mass 0.5 kg falls and sticks to the outer edge of the wheel at the location shown. Just before the impact the clay has speed 8 m/s, and the wheel is rotating clockwise with angular speed 0.27 rad/s. Assume +x is to the right, +y is upward, and +z is out of the page. Assume the line connecting the center to the point of impact is at an angle of 45° from the horizontal.Just after the impact, what is the angular velocity (magnitude and direction) of the wheel?
A person is performing slow arm curls with 10-kgWeight as idicated in the left image of the figure below. The biceps group (consisting of the biceps and brachialis muscles) is the major factor in this exercise. Determine the magnitude F7 of the biceps group force and the magnitude 4 of the elbow joint reaction at point E for the forearm position. The free body diagram is shown in the right image of the figure. Take the dimensions shown to locate the effectivepoints of application of the biceps group; these points are 200 mm directly above E and 50 mm directly to the right of E. Include the eftect of the the 1.5-kg forearm mass with mass center at point G. Assuming that humerus is perfectly vertical and fixed; therefore, the elbow joint E is acting like pin connection. The forearm (E-B-G-C) is perfectly horizontal; therefore, the angle A-E-B is 90 deg.
