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 clockwise 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)2r (ω₁ + ω₂)r ω₁.ω₂.r (ω₁ - ω₂)r (ω₁ - ω₂)2r (ω₁ + ω₂)r ANSWER DOWNLOAD EXAMIANS APP

Theory of Machine A body of weight W is required to move up the rough inclined plane whose angle of inclination with the horizontal is α. The effort applied parallel to the plane is given by (where μ = tan φ = Coefficient of friction between the plane and the body) P = W (sin α + μ cos α) P = W tan α P = W (cos α + μ sin α) P = W tan (α + φ) P = W (sin α + μ cos α) P = W tan α P = W (cos α + μ sin α) P = W tan (α + φ) ANSWER DOWNLOAD EXAMIANS APP
