If two rods of lengths and having coefficients of linear expansion and respectively are connected end-to-end, then find the average coefficient of linear expansion of the composite rod.
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
∆δL=α∆TL ∆δ2L=2α∆T2L The rods are connected end to end means in series, therefore, net change in length after the composition of rods,…
