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) \(\frac{1}{3}\) of tension \(\left(T_{1}\right)\) on the tight side

(b) \(\frac{1}{3}\) of total tension \(\left(T_{t}\right)\) on the tight side

(c) \(\frac{1}{3}\) of the tension \(\left(T_{2}\right)\) on the slack side

(d) \(\frac{1}{3}\) of sum of tensions \(T_{1}\) and \(T_{2}\) i.e. \(\frac{1}{3}\left(T_{1}+T_{2}\right)\).
