Chapter 6, Problem 6/049 The 2.4-kg collar at C has an outer diameter of 85 mm and is press fitte...
Current Attempt in Progress The 37-kg spool of outer radius ro - 450 mm has a centroidal radius of gyration k = 275 mm and a central shaft of radius r; = 160 mm. The spool is at rest on the incline when a tension T = 362 N is applied to the end of a cable which is wrapped securely around the central shaft as shown. Determine the acceleration a of the spool center G and the friction force...
Chapter 6, Problem 6/160 The motor at B supplies a constant torque M which is applied to a 395-mm-diameter internal drum around which is wound the cable shown. This cable then wraps around a pulley which has a mass of 86 kg and is attached to a cart which has a mass of 120 kg carrying 515 kg of rock. The motor is able to bring the loaded cart to a cruising speed of 2.7 m/s in 5 seconds. What...
2. In the mechanism shown, each of the two wheels has a mass of 30 kg and a centroidal radius of gyration of 100 mm. Each link OB has a mass of 10 kg and may be treated as a slender bar. The 7 - kg collar at B slides on the fixed vertical shaft with negligible friction. The spring has a stiffness k = 30 kN/m and is contacted by the bottom of the collar when the links reach...
Chaptar 6, Problem 6/160 Th motor at 8 supplies a constant torque which is applied to a 355-mm-diameter internal drum around whch is wound the cable shown. This cable then wraps around a pulley which has a mass of 90 kg and is attached to a cart which has a mass of 120 kg carrying 695 kg of rock. The motor is able to bring the loaded cart to a cruising speed of 1.5 m's in 2 seconds What torque...

3. Power transmission is an important engineering application and relies on the integrity of the shaft designs. Assume a solid, circular steel shaft with a uniform diameter d 50 mm and a total length I3 m. At its midpoint, a belt passes over a pulley and delivers 50 kW power to the shaft. This power is used to drive two machines at either end of the shaft. Machine 1 consumes P1 20 kW and machine 2 uses P230 KW. The...
