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 Average tension of the tight side and slack side of the belt Tension in the tight side of the belt Sum of the tensions on the tight side and slack side of the belt Tension in the slack side of the belt Average tension of the tight side and slack side of the belt Tension in the tight side of the belt Sum of the tensions on the tight side and slack side of the belt Tension in the slack side of the belt ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In multi V-belt transmission, if one of the belt is broken, we have to change the All the belts There is no need of changing any one as remaining belts can take care of transmission of load Broken belt and its adjacent belts Broken belt All the belts There is no need of changing any one as remaining belts can take care of transmission of load Broken belt and its adjacent belts Broken belt ANSWER DOWNLOAD EXAMIANS APP
