The maximum power can be transmitted when the centrifugal tension is

Question

The power transmitted by a belt is dependent on the centrifugal effect in the belt. The maximum power can be transmitted when the centrifugal tension is

(a) 1/3 of tension ($T_{1}$) on the tight side

(b) 1/3 of total tension  ($T_{t}$) on the tight side

(c) 1/3 of the tension  ($T_{1}$) and ($T_{2}$) on the slack side

(d) 1/3 of sum of tension  ($T_{1}$) and ($T_{2}$)  i.e,1/3(($T_{1}$)+($T_{1}$))
