A uniform rod of length $L$ , density $ρ$ and modulus $Y$ fits between vertical walls separated by $L$ . Friction coefficient is $μ$ . Minimum thermal strain preventing it from falling is:

Options:

Answer:

Solution:

$N = Y A ϵ_{th}$ at each wall.

$2 μ N = ρ A Lg$ .

$ϵ_{th, min} = \frac{ρ Lg}{2 μ Y}$ .
