PART ^

Answer any two full questions, each carries 20 marks.

Design a hollow shaft carrying a spur gear at its free end, having an overhung

of 300mm from the nearest bearing. The pitch circle diameter of the gear is

280mm and transmits 50kW at 2000rpm. Take weight of the gear as 100N.

What is surging of helical springs? Explain.

Design a helical compression spring to support a load of 800N with a

maximum deflection of 24mm.
