A solid rod is just fits between two walls having gap of 2m. If the temperature increases by 50°C then the thermal stress developed in Gap is? Given that, `Y = 3 xx 10^(11) N//m^(2), alpha = 2 xx 10^(-4)// ""^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
`03.00`
`sigma = Y prop Delta T = 3 xx 10 ^(11) xx 2 xx 10 ^(-4)`
`therefore sigma = 3 xx 10 ^(9) Pa `
