An automotive engine develops maximum torque at a speed of 1000
rpm At this speed, the power developed by the engine is 25 kW. The
engine is equipped with a single plate clutch having two pairs of
friction surfaces. The mean diameter of the friction disk is 190 mm
and the coefficient of friction is 0.35. Six springs, with a spring
index of 6, provide the necessary axial force. The springs are made
of patented and cold-drawn steel wires of...
