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) [(r² + R²) sinφ]/2 [(r² + R²) cosφ]/2 [(r + R) cosφ]/2 [(r + R) sinφ]/2 [(r² + R²) sinφ]/2 [(r² + R²) cosφ]/2 [(r + R) cosφ]/2 [(r + R) sinφ]/2 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A shaft has an attached disc at the centre of its length. The disc has its centre of gravity located at a distance of 2 mm from the axis of the shaft. When the shaft is allowed to vibrate in its natural bow-shaped mode, it has a frequency of vibration of 10 rad/s. When the shaft is rotated at 300 r.p.m., it will whirl with a radius of 2.50 mm 2.22 mm 3.0 mm 2 mm 2.50 mm 2.22 mm 3.0 mm 2 mm ANSWER DOWNLOAD EXAMIANS APP
