A shaft is required to transmit 1 MW power at 240 rpm. The shaft must not twist more than 1 degree on a length of one meter. If the modulus of rigidity for the material of shaft is 80 kN/mm2. Find the diameter of shaft and shear stress induced on it.

Torque transmitted by the shaft T= Px60/2π N= 1X106X60/2 π x240  = 39783.58 Nm  =39783.58 x 103 N.mm We know that T/J=GΘ/L or J=TXL/GXΘ…

Graphical Representation of Displacement with Respect to Time

The displacement of a moving object in a given time may be given by means of a graph. Such a graph is drawn by plotting the displacement as ordinate …
