Theory of Machine When the belt is stationary, it is subjected to some tension known as initial tension. The value of this tension is equal to the Sum of the tensions on the tight side and slack side of the belt Tension in the tight side of the belt Average tension of the tight side and slack side of the belt Tension in the slack side of the belt Sum of the tensions on the tight side and slack side of the belt Tension in the tight side of the belt Average tension of the tight side and slack side of the belt Tension in the slack side of the belt ANSWER DOWNLOAD EXAMIANS APP
