Abstract: Thus when 0 is 90", the velocity is zero, whilst maximum velocity (or) is achieved when 0 is 0". From a knowledge of the speed of rotation of the shaft, and the time interval represented by each line on the computer printout, the angular displacement 0 and hence the punch velocity can be calculated for any point in time represented by a given line on the computer printout.Hence the overall power expended can be calculated by summation of the products of the force and the corresponding velocity.The use of powe…
