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 Tension in the slack side of the belt Sum of the tensions on the tight side and 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 Tension in the slack side of the belt Sum of the tensions on the tight side and slack side of the belt ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A shaft has an attached disc at the centre of its length. The disc has its centre of gravity located at a distance of 2 mm from the axis of the shaft. When the shaft is allowed to vibrate in its natural bow-shaped mode, it has a frequency of vibration of 10 rad/s. When the shaft is rotated at 300 r.p.m., it will whirl with a radius of 2 mm 3.0 mm 2.22 mm 2.50 mm 2 mm 3.0 mm 2.22 mm 2.50 mm ANSWER DOWNLOAD EXAMIANS APP
