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 [(r² + R²) sinφ]/2 [(r + R) sinφ]/2 [(r + R) cosφ]/2 [(r² + R²) cosφ]/2 [(r² + R²) sinφ]/2 [(r + R) sinφ]/2 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The equation of motion for a vibrating system with viscous damping is (d²x/dt²) + (c/m). (dx/dt) + (s/m). x = 0. If the roots of this equation are real, then the system will be Over-damped Under damped Without vibrations Critically damped Over-damped Under damped Without vibrations Critically damped ANSWER DOWNLOAD EXAMIANS APP
