A cylinder has a piston at temperature of . There is all round clearance of between the piston and cylinder wall if internal diameter of the cylinder is . What is the temperature at which piston will fit into the cylinder exactly? and
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
For the piston to get fit exactly into the cylinder, the thermal expansion of the piston should be 0.08 mm from both sides along the diameter of piston, therefore, total clearance should be δ=2×0.08 mm=0.16 mm Now, using the formula for linear…
