A rod of length L is pivoted at one end and is rotated with as uniform angular velocity in a horizontal plane. Let T1 and T2 be the tensions at the points L/4 and 3L/4 away from the pivoted ends. T1>T2 T2>T1 T1=T2 The relation between T_1 and T_2` depends on whether the rod rotates clockwise or anticlockwise.
