Speed=2000rpm
Design a cast iron cylinder for an IC engine whose bore diameter is 80mm and (15)
the maximum combustion pressure is 5.5MPa.
A 80 mm diameter full journal bearing support a radial load of 600N. The speed (15)
of the shaft = 1200rpm. Design the bearing.
PART B
Answer any two full questions, each carries 15 marks.

A single dry plate clutch is to be designed to transmit 8 kW at 1000 rpm. (15)

Find out the clutch dimensions assuming the ratio of the mean radius to the face

width as 4.

Also design spring for the same.

A multi plate disc clutch transmit 4kW at 1000rpm.The outer radius is limited 10 (15)

65mm.Assume any suitable material and design the clutch.
