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 [(r + R) cosφ]/2 [(r² + R²) cosφ]/2 [(r² + R²) sinφ]/2 [(r + R) sinφ]/2 [(r + R) cosφ]/2 [(r² + R²) cosφ]/2 [(r² + R²) sinφ]/2 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In the below figure, PC is the connecting rod and OC is the crank making an angle θ with the line of stroke PO and rotates with uniform angular velocity at ω rad/s. The Klien's acceleration diagram for determining the acceleration of the piston P is shown by quadrilateral CQNO. The acceleration of the piston P with respect to the crank-pin C is given by ω² × CO ω² × CN ω² × NO ω² × QN ω² × CO ω² × CN ω² × NO ω² × QN ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A system in dynamic balance implies that There is no critical speed in the system There will absolutely no wear of bearings The system is also statically balanced The system is critically damped There is no critical speed in the system There will absolutely no wear of bearings The system is also statically balanced The system is critically damped ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine When the load on the engine increases, it becomes necessary to increase the supply of working fluid and when the load decreases, less working fluid is required. The supply of the working fluid to the engine is controlled by a Governor D-slide valve Flywheel Meyer's expansion valve Governor D-slide valve Flywheel Meyer's expansion valve ANSWER DOWNLOAD EXAMIANS APP
