Theory of Machine The essential condition of placing the two masses, so that the system becomes dynamically equivalent, is (where l₁ and l₂ = Distance of two masses from the centre of gravity of the body, and kG = Radius of gyration of the body) l₁ = kG l₁l₂ = kG l₁l₂ = kG² l₂ = kG l₁ = kG l₁l₂ = kG l₁l₂ = kG² l₂ = kG 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) 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
