Question 2
A solid round bar 6 cm in diameter and 250 cm long is used as a strut. One end of the strut is fixed while its other end is hinged. The safe compressive load for strut using Euler’s formula, assuming E = 200 GPa and factor of safety = 2 is
Question 3
A cantilever beam of length L and flexural modulus EI is subjected to a point load P at the free end. The elastic strain energy stored in the beam due to bending (neglecting transverse shear)
Question 4
A steel bar(α= 11x10-6) is held by two fixed supports as shown in the figure and is subjected to an increase of temperature ∆T=100 °C and young's modulus 200GPa respectively, the magnitude of thermal stress (in MPa) induced in the bar is _____ 
Question 5
A solid aluminum shaft, 5 cm diameter and 1 m long, is to be replaced by a tubular steel shaft of the same length and the same outside diameter (i.e. 5 cm), such that each of the two shaft could have the same angle of twist per unit torsional moment over the total length. Modulus of rigidity of steel is three times that of aluminium. The inner diameter of the tubular shaft is
