Theory of Machine An involute pinion and gear are in mesh. If both have the same size of addendum, then there will be an interference between the Flanks of both gear and pinion Tip of the gear tooth and flank of pinion Tip of both gear and pinion Tip of the pinion and flank of gear Flanks of both gear and pinion Tip of the gear tooth and flank of pinion Tip of both gear and pinion Tip of the pinion and flank of gear 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
Theory of Machine The swaying couple is maximum or minimum when the angle of inclination of the crank to the line of stroke (θ) is equal to 45° and 225° 90° and 180° 180° and 270° 270° and 360° 45° and 225° 90° and 180° 180° and 270° 270° and 360° ANSWER DOWNLOAD EXAMIANS APP
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) sinφ]/2 [(r + R) cosφ]/2 [(r² + R²) sinφ]/2 [(r² + R²) cosφ]/2 [(r + R) sinφ]/2 [(r + R) cosφ]/2 ANSWER DOWNLOAD EXAMIANS APP
