When an automobile makes a left turn, the gyroscopic torque increases the forces on the outer wheels. The correct answer is (a) increases the forces on the outer wheels.
This occurs due to the gyroscopic effect of rotating wheels. As the vehicle changes direction, the gyroscopic couple produces a torque that acts perpendicular to both the angular momentum and the precession axis. This gyroscopic torque adds to the normal load on the outer wheels and reduces it on the inner wheels.
Key points:
- Gyroscopic torque is produced by the rotating wheels
- During a left turn, the outer wheels experience increased load
- This effect is significant in high-speed maneuvers
- It affects vehicle stability and handling characteristics
