Theory of Machine The advantage of the piston valve over the slide valve is that in the former case Wear is less Both wear and power absorbed are low Power absorbed is less The pressure developed being high provides tight sealing Wear is less Both wear and power absorbed are low Power absorbed is less The pressure developed being high provides tight sealing 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) [(r + R) cosφ]/2 [(r² + R²) cosφ]/2 [(r + R) sinφ]/2 [(r² + R²) sinφ]/2 [(r + R) cosφ]/2 [(r² + R²) cosφ]/2 [(r + R) sinφ]/2 [(r² + R²) sinφ]/2 ANSWER DOWNLOAD EXAMIANS APP
