A power shaft runing at a steady speecl of lZ5 rev/min clriies a countershaft
through a single-plate friction clutch of external and internal diameters
375 and 225 mm respectively. Tho masses on the countershaft have a radius of
gpation of 250 mm and a, total mass of 350 kg. The axial spring load operating
the clutch is 450 N, ar::d. p :0.3. Assuming uniform acceleration,'determine
the time required to reach full speetl from rest, and the work dissipated due to
clritch slip during that time.
