A power shaft running at a steady speed of 175 rev/min drives a counter- shaft through a single-plate friction clutch of external and internal diameters 375 and 225 mm respectively. The masses on the countershaft have a radius of gyration of 250 mm and a total mass of 350 kg. The axial spring load operating the clutch is 450 N, and p the time required to reach full speed from rest, and the work dissipated due to clutch slip during that time. (U. Lond.) 0-3. Assuming uniform acceleration, determine (Ans. : 9-9 s; 3-67 kJ)
