Theory of Machine The frictional torque transmitted in a conical pivot bearing, considering uniform pressure, is (where R = Radius of shaft, and α = Semi-angle of the cone) μ W R cosecα (3/4) μ W R cosecα (1/2) μ W R cosecα (2/3) μ W R cosecα μ W R cosecα (3/4) μ W R cosecα (1/2) μ W R cosecα (2/3) μ W R cosecα ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The static balancing is satisfactory for low speed rotors but with increasing speeds, dynamic balancing becomes necessary. This is because, the Effects of unbalances are directly proportional to the speed Unbalanced forces are not dangerous at higher speeds Effects of unbalances are proportional to the square of the speed Unbalanced couples are caused only at higher speeds Effects of unbalances are directly proportional to the speed Unbalanced forces are not dangerous at higher speeds Effects of unbalances are proportional to the square of the speed Unbalanced couples are caused only at higher speeds ANSWER DOWNLOAD EXAMIANS APP
