Properties Of Solids And Liquids Question 535

Question: At $15^{\circ} C,$ a wheel has diameter of 30 cm and inside diameter of a steel rim is 29.9 cm. Coefficient of thermal expansion of steel is $1.2 \times 10^{- 5} /^{o} C$ . To what temperature, the rim must be heated so that it can slip over wheel?

Options:

A) $2787^{\circ} C$

B) $2772^{\circ} C$

C) $2529^{\circ} C$

D) $2802^{\circ} C$

Show Answer

Answer:

Correct Answer: D

Solution:

Rim will slip if its diameter increases to 30 cm. Hence $Δ l = 0.1 c m$

$Δ T = \frac{Δ l}{l \times a} = \frac{0.1}{29.9 \times 1.2 \times 10^{- 5}} = 2787^{o} C$

Rim to be heated to temperature

$2787 + 15 = 2802^{o} C$
