  • Question 1/10
    4 / -1
    An area of cross-section of rubber string is 2 cm2. Its length is doubled when stretched with a linear force of 2 × 105 dynes. The Young\'s modulus of the rubber in dyne/cm2 will be
    Solutions

  • Question 2/10
    4 / -1
    The temperature of a wire of length 1 m2 and area of cross-section 1 cm is increased from 0°C to 100°C. If the rod is not allowed to increase in length, the force required will be (a = 10–5/°C and Y = 1011 wm2)

  • Question 5/10
    4 / -1
    Two wires of copper having the length in the ratio 4 : 1 and their radii ratio as 1 : 4 are stretched by the same force. The ratio of longitudinal strain in the two will be
    Solutions

  • Question 6/10
    4 / -1
    A weight of 200 kg is suspended by vertical wire of length 600.5 cm. The area of cross-section of wire is 1 mm2. When the load is removed, the wire contracts by 0.5 cm. The Young\'s modulus of the material of wire will be
