Theory of Machine In a steam engine, one method of obtaining the earlier cut-off with a simple slide valve is by increasing the angle of advance of the eccentric while the throw of the eccentric, steam lap and exhaust lap are kept constant. This method will Reduce maximum opening of port to steam All of these Cause withdrawing or throttling of steam Reduce length of effective stroke of piston Reduce maximum opening of port to steam All of these Cause withdrawing or throttling of steam Reduce length of effective stroke of piston ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a Hartnell governor, the stiffness of the spring is given by (where S1 and S2 = Spring forces exerted on the sleeve at max. and min. radii of rotation, and h = Compression of the spring) (S₁ + S₂) / h (S₁ + S₂) / 2h (S₁ - S₂) / 2h (S₁ - S₂) / h (S₁ + S₂) / h (S₁ + S₂) / 2h (S₁ - S₂) / 2h (S₁ - S₂) / h ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The acceleration of a particle at any instant has two components i.e. radial component and tangential component.
