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 Tension in the slack side of the belt Sum of the tensions on the tight side and 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 Tension in the slack side of the belt Sum of the tensions on the tight side and slack side of the belt ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A torsional system with discs of moment of inertia I₁ and I₂ as shown in the below figure, is gear driven such that the ratio of speed of shaft B to shaft A is 'G'. Neglecting the inertia of gears, the equivalent inertia of disc on shaft B at the speed of shaft A is equal to G.I₂ G².I₂ I₂/G² I₂/G G.I₂ G².I₂ I₂/G² I₂/G ANSWER DOWNLOAD EXAMIANS APP
