Question 1
The reading of a spring balance is from 0 to 200 N and is 10 cm long. A body suspended from the spring balance is observed to oscillate vertically at 2 Hz. The mass of the body is nearly
Question 2
For two bodies having direct impact, coefficient of restitution is given by ______.
Question 3
Two metallic blocks having masses in the ratio 2:3 are made to slide down a friction less inclined plane starting initially from rest position. When these blocks reach the bottom of the inclined plane, they will have their kinetic energies in the ratio
Question 4
Two blocks with masses M and m are in contact with each other and are resting on a horizontal frictionless floor. When horizontal force F is applied to the heavier, the blocks accelerate to the right. The force between the two blocks are
Question 5
A three bar truss to resist a service load P = 100 kN is shown in the figure. Use a load factor of 2 and consider all three members to have equal cross-section areas. The yield stress of the material of which the members are fabricated is 400 MPa. The area of cross section of each truss member is
