Syllabus

Module-1 :
1. A cone clutch has a cone angle of 300 and is used to transmit 10 kW at 1500rpm. The width of the face is one-fourth of the mean diameter of friction lining. The normal intensity of pressure between contact surfaces is 0.12 MPa and coefficient of friction is 0.2, assuming uniform wear, design the clutch dimensions. (25 marks)
OR

2. A differential band brake has an operating lever 240mm long. The ends of the band are attached at 40mm and 120mm on either side of the pivot. The drum diameter is 600mm. Arc of contact is 3000. Design the brake to absorb 15kWat 1200 rpm. (25 marks)

Module-2 :
