Question

If a cylinder of diameter 1.0 cm at 30°C is to be
solid into a hole of diameter 0.9997 cm in a steel
plate at the same temperature, then minimum
required rise in the temperature of the plate is :
(Coefficient of linear expansion of steel
= 12x100/°C)
Va 25°C
(b) 35°C
(c) 45°C
(d) 55°C​

Answer 1

Answer:

cylinder of diameter 1.00cm at 30°C is to be slid into a hole in a steel plate. The hole has a diameter of 0.99970 cm at 30°C. To what temperature must the plate be heated? The coefficient of linear expansion for steel is 1.1×10^-5 °C^-1.
