If a cylinder of diameter 1 cm at 30

Asked by admin @ in Physics viewed by 331 People

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)

Answered by admin @


Answer:

0.25x10∧-6 C°

Explanation:

ΔR = 1 - 0.9997 ÷ 2 = expansion in radius = 1.5x10∧-4 cm

1.5x10∧-4 = αRΔT

ΔT = 1.5x10∧-4 /  αR = 1.5x10∧-4 /  12×10²x0.5 = 0.25x10∧-6 C°
