Theory of Machine The relation between number of pairs (p) forming a kinematic chain and the number of links (l) is l = 2p - 3 l = 2p - 2 l = 2p - 4 l = 2p - 5 l = 2p - 3 l = 2p - 2 l = 2p - 4 l = 2p - 5 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) / 2h (S₁ - S₂) / h (S₁ + S₂) / 2h (S₁ + S₂) / h (S₁ - S₂) / 2h (S₁ - S₂) / h (S₁ + S₂) / 2h (S₁ + S₂) / h ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a screw jack, the effort required to lift the load W is given by (where α = Helix angle, and φ = Angle of friction) P = W tan(φ - α) P = W cos(α + φ) P = W tan(α - φ) P = W tan(α + φ) P = W tan(φ - α) P = W cos(α + φ) P = W tan(α - φ) P = W tan(α + φ) ANSWER DOWNLOAD EXAMIANS APP
