Question

hollow shaft of diameter ratio 3/8 (Internal dia, di to external dia, do) is to transmit P kW
power at 100 rpm. The maximum torque can be 20% greater than the mean (obtained from
power transmission requirement). The shear stress is not to exceed 60 N/mm2
and twist in a
length of 4 m not to exceed 2o
. Calculate its external and internal diameters which would satisfy
both the above conditions. Assume modulus of rigidity G = 0.85 × 105
N/mm2
. P=350+XX (XX
is the last two digit of your Roll No) e.g. for 1906302, P=352 kW.
