Theory of Machine In a four-bar chain it is required to give an oscillatory motion to the follower for a continuous rotation of the crank. For the lengths of 50 mm of crank and 70 mm of the follower, determine theoretical maximum length of coupler. The distance between fixed pivots of crank and followers is 45 mm Slightly less than 95 mm Slightly more than 95 mm 95 mm 45 mm Slightly less than 95 mm Slightly more than 95 mm 95 mm 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) 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 [(r² + R²) sinφ]/2 ANSWER DOWNLOAD EXAMIANS APP
