```										Dear manoj
let mass per unit length of rod is m
and take a strip of lenghth dx at a distance x from the pivoted end
tension in rod is due to centrifugal force in part of rod that is away from the point of interest
so for point at a distance L/4

T1  = limit  L/4 to L    ∫ (mdx)w2 x
=15/32 mw2L2

For a point at 3L/4
T2  = limit  3L/4 to L    ∫ (mdx)w2 x
=7/32 mw2L2

So  T1>T2
