The stiffness of the spring in a hartnell governor is equal to $$S_{1}$$ = Spring force exerted on the slleve at maximum radius of rotation $$S_{2}$$= Spring force exerted on the slleve at minimum radius of rotation
A sliding bearing which can support steady loads without any relative motion between the journal and the bearing is called
Form the Lewis equation Fb = f.p.y.b, the strength factor of the gear is given by the product
A simply supported beam is subjected to a point load P at the middle of the beam. The correct normal stress distribution across its cross-section is given by which figure?
The shear strength, tensile strength and, compressive strength of rivet joint are 100N, 120N and 150N respectively. If strength of the unriveted plate is 200N, the efficiency of rivet joint is
