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 Tension in the tight side of the belt Average tension of the tight side and slack 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 Tension in the tight side of the belt Average tension of the tight side and slack 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 two links OA and OB are connected by a pin joint at O. If the link OA turns with angular velocity ω₁ rad/s in the clockwise direction and the link OB turns with angular velocity ω₂ rad/s in the anticlockwise direction, then the rubbing velocity at the pin joint O is (where r = Radius of the pin at O) (ω₁ - ω₂) 2r ω₁.ω₂.r (ω₁ + ω₂) r (ω₁ - ω₂) r (ω₁ - ω₂) 2r ω₁.ω₂.r (ω₁ + ω₂) r (ω₁ - ω₂) r ANSWER DOWNLOAD EXAMIANS APP
