Question 1
If the diameter of a circular column is reduced by 10%. Then the percentage reduction in the Euler’s crippling load is
Question 2
A beam of circular section is subjected to a load of 4kN. If the diameter of the circular section is 0.1m. Calculate the maximum shear stress.
Question 3
A cantilever beam of length 2 m is acted upon by a concentrated load of 450 N (downward) at the free end and a load P (downward) at the mid-point. If the deflection at the free end of the beam is 15 mm, then the value of load P is _______(N)
(E = 10 GPa and I = 107 mm4)
Question 4
A bar of 30mm diameter is subjected to pull of 60kN. The measured extension on gauge length of 200mm is 0.1mm and change in diameter is 0.004mm. Calculate bulk modulus (MN/mm2 ). (put the value upto two decimal place)
Question 5
In a two dimensional stress analysis, the state of stress at a point is as shown below,
The magnitude of ‘
’ is
The magnitude of ‘
’ is Question 6
A copper bar of 25 cm length is fixed by means of supports at its ends. Supports can yield (total) by 0.01 cm. If the temperature of the bar is raised by 100 °C, then the stress induced in the bar for if αc = 20×10-6/°C and Ec = 0.5×105 MPa will be
