Calculate the velocity of the wheel if the angular speed is 25 rad/s and radius is 10 m.

Calculate the velocity of the wheel if the angular speed is 25 rad/s and radius is 10 m. Correct Answer 250 m/s

The velocity of the wheel can be calculated using the relation V=ω×r. The velocity is the vector product of angular speed and radius. V=Ω×r = 25×10 = 250 m/s.

The two links OA and OB are connected by a pin joint at O. If the link OA turns with angular velocity $${\omega _1}$$ rad/s in the clockwise direction and the link OB turns with angular velocity $${\omega _2}$$ rad/s in the clockwise direction, then the rubbing velocity at the pin joint O is (where r = Radius of the pin at O)
