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

Theory of Machine A rotor which is balanced statically but not dynamically is supported on two bearings L apart and at high speed of the rotor, reaction on the left bearing is R. The right side of the bearing is shifted to a new position 2L apart from the left bearing. At the same rotor speed, dynamic reaction on the left bearing in the new arrangement will Become equal to R/4 Become equal to 2R Remain same as before Become equal to R/2 Become equal to R/4 Become equal to 2R Remain same as before Become equal to R/2 ANSWER DOWNLOAD EXAMIANS APP
