Theory of Machine When the addenda on pinion and wheel is such that the path of approach and path of recess are half of their maximum possible values, then the length of the path of contact is given by (where r = Pitch circle radius of pinion, R = Pitch circle radius of wheel, and φ = Pressure angle) [(r + R) sinφ]/2 [(r² + R²) sinφ]/2 [(r + R) cosφ]/2 [(r² + R²) cosφ]/2 [(r + R) sinφ]/2 [(r² + R²) sinφ]/2 [(r + R) cosφ]/2 [(r² + R²) cosφ]/2 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/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 Become equal to R/4 ANSWER DOWNLOAD EXAMIANS APP
