The two cylindrical rod segments are fixed to the rigid walls such that there is a gap of 0.01 in. between them when t1 = 60°f. each rod has a diameter of 1.25 in. determine the average normal stress in each rod if t2 = 400°f, and also calculate the new length of the aluminum segment.

The sun’s mass is 2.0×10^ 30 kg, its radius is 7.0×10 5 km, and it has a rotational period of approximately 28 days. if the sun should collapse into a white dwarf of radius 3.5×10 3 km, what would its period be if no mass were ejected and a sphere of uniform density can model the sun both before and after?
