A steel rod (Es = 210 GPa, dr = 12 mm, ̑ = 12 x 10^-6 / °C) is held stress free between rigid walls by a clevis and pin (dp = 15 mm) assembly at each end as shown in the figure. If the allowable shear stress in the pin is 45 MPa and the allowable normal stress in the rod is 70 MPa, calculate the maximum permissible temperature drop ΔT.

00:02 So as given in the question, if there is a temperature drop, the road will have thermal stresses in it.
00:12 So when we are decreasing the temperature, what happens is the road tends to shrink and there will be compressive stresses in the, induced in the road.
00:24 So we know that sigma t .h is equal to alpha into delta t...
