(Meriam and Kraige 6th ed. 6/89) The spool (ro = 0.2 m, ri = 0.075 m) has a mass of 25 kg and radius of gyration kg = 175 mm. Constant force Tis applied at an angle 0 to a cord securely wrapped around the inner radius as T то TI G shown. If T = 50 N, 0 = 30°, and friction coefficients with the ground surface u, = 0.10 and uk = 0.08, find the angular acceleration of the disk, the acceleration of its center of mass G, and the friction force which the surface exerts on the spool. Assume that the spool is initially at rest. (Answers: 0.3 rad/s [CCW], 1.0 m/s [ ] 18 N[-])
A large symmetrical drum for drying sand is operated by the geared motor drive shown. If the mass of the sand is 640 kg and an average gear-tooth force of 2.55 kN is supplied by the motor pinion A to the drum gear normal to the contacting surfaces at B, calculate the average offset of the center of mass G of the sand from the vertical centerline. Neglect all friction in the supporting rollers. Assume r = 150 mm, R= 630 mm, 0 = 15% Detail of contact at B Answer: x= i B 14 ! mm

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 uniform, solid cylinder of mass mc=7.42 kg and radius R=.26 m with Icm=1/2MR^2 is attached at its axle to a string. The string is wrapped around a small ideal pulley and is attached to a hanging block of mass mb=2.73 kg as indicated in the figure above. You release the objects from rest and the cylinder rolls without slipping. What is the magnitude of the acceleration of the block?
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.
