Question 1

A solid shaft of circular cross-section is Subjected to a torque T, which produces a maximum Shear stress $Description: Description: Practice-Set-4_files\image098.png$ in the shaft. The diameter of shaft should be

Question 2

With one fixed end and other free end, a column of length L buckles at load P. Another column of same length and same cross section fixed at both ends buckles at load Q. the ratio of P/Q is

Question 3

A shaft is said to be in pure torsion if

Question 4

Consider a steel (Young's modulus E = 200 GPa) column hinged on both sides. Its height is 1.0 m and cross-section is 10 mm × 20 mm. The approximate lowest Euler critical buckling load (in kN) is__________

Question 5

Torsion bars are in parallel

Question 6

A helical compression spring made of wire of circular cross-section is subjected to a compressive load. The maximum shear stress induced in the cross-section of the wire is 24 MPA. For the same compressive load, if both the wire diameter and the mean coil diameter are doubled, the maximum shear stress (in MPa) induced in the cross-section of the wire is _______

Question 7

Rankine’s formula for critical load is given by

Question 8

The diameter of shaft 1 is thrice the diameter of shaft 2 and both are made of the same material. Assuming both the shafts to rotate at the same speed, the maximum power transmitted by 2 is_____.
