Question 1

A two-member truss PQR is supporting a load W. The axial forces in members PQ and QR are respectively

Question 2

For the loading on truss shown in the figure, the force in member CD is

Question 3

Consider a truss PQR loaded at P with a force F as shown in the figure.

The tension in the member QR is

Question 4

A Hook’s joint is used to connect two

Question 5

The ratio of tension on the tight side to that on the slack side in a flat belt drive is:

Question 6

A heavy block of mass m is slowly placed on a conveyer belt moving speed v . If coefficient of friction between block and the belt is , the block will slide on the belt through distance

Question 7

Two blocks with masses M and m are in contact with each other and are resting on a horizontal frictionless floor. When horizontal force is applied to the heavier, the blocks accelerate to the right. The force between the two blocks are

Question 8

Ratio of the radii of the planes and is k and ratio of the accelerations due to gravity on them is s. Ratio of escape velocities from them will be

Question 9

A pin jointed uniform rigid rod of weight W and length L is supported horizontally by an external force F as shown in the figure below. The force F is suddenly removed. At the instant of force removal, the magnitude of vertical reaction developed at the support is

Question 10

The figure shows a pin-jointed plane truss loaded at the point M by hanging a mass of 100 kg. The member LN of the truss is subjected to a load of
