Q6. A cable is unwound from a spool supported on small rollers at A and B by exerting a force T = 350 N on the cable. The spool and the cable have a total mass of 610 kg and a radius of gyration of k, = 1.2 m. Neglect the mass of the cable being unwound and the mass of the rollers at A and B. The rollers turn without friction (a) The spool subjected to four external forces. List all of them. (b) Draw free body diagram of the system. Include all the relevant information in the drawing (c) Determine the time needed to unravel 8 m of cable from the spool. T=300NO 300 OO Figure 26
