Question
Gear A in (Figure 1) is spinning such that its rotational velocity vector points in the negative x direction. It is lowered so that its edge comes in contact with the edge of gear B.
What is the direction of the rotational velocity caused by the force that A exerts on B?
A)The rotational velocity of gear B is in the negative y direction.
B)The rotational velocity of gear B is in the positive y direction.
C)The rotational velocity of gear B is in the positive x direction.
D)The rotational velocity of gear B is in the negative x direction.
Explanation / Answer
Gears in contact travel in opposite directions. Hence, it is towards the NEGATIVE X DIRECTION. [OPTION D, ANSWER]
