Question 2

Two shafts A and B are made of the same material. If the diameter of shaft B is twice that of shaft A, then the ratio of power which can be transmitted by shaft A to that of shaft B is

Question 3

In a propeller shaft a torque is applied. Due to this torque maximum compressive direct stress of 30 and maximum shear stress of 70 induced in a shaft, then the maximum tensile stress will be

Question 4

A solid circular shaft of diameter d and length L is fixed at one end and free at the other end. A torque T is applied at the free end. The shear modulus of the material is G. The angle of twist at the free end is

Question 5

A channel section of uniform thickness 5cm used as a beam. Moment of inertia of channel Ixx is equal to 51927.08 cm4 and point C is shear centre; then value of e in cm is

Question 6

Wall thickness of a thin cylinder shell of 800 mm internal diameter is 10 mm. length of the cylinder is 2m. if the shell is subjected to an internal pressure of 1.5 MPa, determine the maximum shear stress.

Question 7

A cantilever of length L, carries three loads W each at an interval of L/3 as shown in figure. If EI is flexural rigidity, then the slope at free end D is where is _____

Question 8

The deflection at the free end of cantilever of span L due to point load at free end is observed to be . The strain energy stored in the bar will be

Question 9

A simply supported beam with width b and depth d carries a central load W and undergoes deflection at centre. If the width and depth are interchanged, then the deflection at the centre of the beam would attain the value

Question 10

A two-span continuous beam having equal spans each of length L is subjected to a uniformly distributed load w per unit length. The beam has constant flexural rigidity. The reaction at the middle support is
