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) r (ω₁ + ω₂) r ω₁.ω₂.r (ω₁ - ω₂) 2r (ω₁ - ω₂) r (ω₁ + ω₂) r ω₁.ω₂.r (ω₁ - ω₂) 2r 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
Theory of Machine In multi V-belt transmission, if one of the belt is broken, we have to change the Broken belt and its adjacent belts There is no need of changing any one as remaining belts can take care of transmission of load All the belts Broken belt Broken belt and its adjacent belts There is no need of changing any one as remaining belts can take care of transmission of load All the belts Broken belt ANSWER DOWNLOAD EXAMIANS APP
