A particle of mass m fixed to one end of a light rigid rod of length l is at its lowest position. It is given the minimum horizontal speed necessary to complete the vertical circle. The force in the rod at the lowest position is

TestHub · Accepted Answer

For a rod the minimum bottom speed is u = 2 g l ​ (speed at the top may be zero). ​ Then T − m g = l m u 2 ​ = 4 m g , so T = 5 m g . ​
