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)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 In a steam engine, one method of obtaining the earlier cut-off with a simple slide valve is by increasing the angle of advance of the eccentric while the throw of the eccentric, steam lap and exhaust lap are kept constant. This method will Cause withdrawing or throttling of steam Reduce maximum opening of port to steam Reduce length of effective stroke of piston All of these Cause withdrawing or throttling of steam Reduce maximum opening of port to steam Reduce length of effective stroke of piston All of these ANSWER DOWNLOAD EXAMIANS APP
