Question

When a uniform rod is heated, which of the follwing quantity of the rod will increase​

Answer 1

Answer:

Hola...

Here is your answer mate_____☺️

Explanation:

The moment of inertia of a rod about a perpendicular bisector is ML^2 / 12.

Change in M.I. is d(ML^2 / 12) = ML dL / 6

dL = aL dt

dI = aL dt ML / 6 = 2a(ML^2/12) dt = 2aIdt
