Question 1

The buckling load for a column hinged at both ends is 100 KN. If the ends are fixed, the buckling load changes to

Question 2

The maximum bending stress developed in MPa is

Question 3

The deflection at the free end of cantilever as with load as shown in figure is____ mm.

Load P (500kN) acts at half of the total length 3m. Cross section of beam is circular with diameter 400mm. Elastic modulus of the material of beam is 200GPa.

Question 4

The state of stress at a point is given by

σx = -20 MPa, σy = 90 MPa, τxy = 40 MPa

the angle between principle plane & plane of pure shear will be

Question 5

Find out the outer diameter of the hollow shaft, if the allowable shear stress induced in it is 53MPa and the permissible value of Torque in it is 2000Nm. Take the value of k to be 0.4 where k is the ratio of inner diameter to outer diameter .

Question 6

A thin cylinder of internal dameter 60 mm and will thickness 2mm is subjected to an internal pressure of 1.25 N/mm2. The cylinder is also subjected to a torque of 60 Nm, the axis of the torque coinciding with that of the cylinder . The minor principal stress is MPa.
