A hollow cast iron column 10m long and 10cm internal diameter and 15cm
external diameter is having its one end hinged and other rigidly fixed. Find the
crippling load and safe load taking factor of safety as 5. Take E=95kN/mm’,
Use Eulers formula.

A solid steel shaft has to transmit 75kW at 200rpm. Determine the suitable
diameter of shaft if the maximum torque transmitted is not to exceed the mean
by 30% in each revolution. The shear stress is not to exceed 70N/mm?. Also
calculate the maximum angle of twist in a length of 4m of the shaft. G=80Gpa
A beam of length 6m is simply supported at its ends and carries a point load of
48kN and 406 at a distance of 1൩ and 3m respectively from the left support.
Find a) deflection under each load b) maximum deflection c) point at which
maximum deflection occurs by double integration method. Given
E=2x 10°N/mm/ and I=85x10°mm*.

Define slenderness ratio. State the equations for Euler’s crippling load for
columns with different end conditions.

Explain moment area theorems.
