Theory of Machine When the belt is stationary, it is subjected to some tension known as initial tension. The value of this tension is equal to the Average tension of the tight side and slack side of the belt Tension in the tight side of the belt Sum of the tensions on the tight side and slack side of the belt Tension in the slack side of the belt Average tension of the tight side and slack side of the belt Tension in the tight side of the belt Sum of the tensions on the tight side and slack side of the belt Tension in the slack side of the belt ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The relation between number of pairs (p) forming a kinematic chain and the number of links (l) is l = 2p - 4 l = 2p - 2 l = 2p - 3 l = 2p - 5 l = 2p - 4 l = 2p - 2 l = 2p - 3 l = 2p - 5 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 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) P = W tan(φ - α) ANSWER DOWNLOAD EXAMIANS APP
