Theory of Machine The factional torque for square thread at the mean radius r while raising load W is given by T = W.r tan(φ - α) T = W.r tanα T = W.r tan(φ + α) T = W.r tanφ T = W.r tan(φ - α) T = W.r tanα T = W.r tan(φ + α) T = W.r tanφ ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a four-bar chain it is required to give an oscillatory motion to the follower for a continuous rotation of the crank.
