Theory of Machine The factional torque for square thread at the mean radius r while raising load W is given by T = W.r tanα T = W.r tanφ T = W.r tan(φ - α) T = W.r tan(φ + α) T = W.r tanα T = W.r tanφ T = W.r tan(φ - α) T = W.r tan(φ + α) ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A rotor which is balanced statically but not dynamically is supported on two bearings L apart and at high speed of the rotor, reaction on the left bearing is R. The right side of the bearing is shifted to a new position 2L apart from the left bearing. At the same rotor speed, dynamic reaction on the left bearing in the new arrangement will Become equal to R/4 Become equal to R/2 Remain same as before Become equal to 2R Become equal to R/4 Become equal to R/2 Remain same as before Become equal to 2R ANSWER DOWNLOAD EXAMIANS APP
