Q4/ The contact surfaces in a cone chuch have an effective diameter of 80 mm. The semi-angle of the cone is 15° and coefficieat of friction is 0.3. Find the torque required to produce slipping of the clutch, if the axial force applied is 200 N. The clutch is employed to connect an electric motor, running uniformly at 900 r.p.m. with a flywheel which is initially stationary. The flywheel has a mass of 14 kg and its radius of gyration is 160 mm. Calculate the time required for the flywheel to attain foll-speed and also the energy lost in slipping of the clutch.
