27. What is the function of a gear in power transmission systems?
- To change the direction of rotation
- To eliminate the need for lubrication
- To increase energy losses
- To decrease the efficiency of the system
Answer
The correct answer is: A) To change the direction of rotation
Explanation
Power and motion are transferred between rotating shafts using mechanical components known as gears. Within a mechanical system, they can alter power transmission velocity, torque, and direction.
