Question

The total reaction on the ground when wheels of the vehicle are subjected to the gyroscopic couple and the centrifugal force while negotiating the curve is

• A. Increased on inner wheels and decreased on outer wheels
• B. Decreased on inner wheels and increased on outer wheels
• C. Decreased on all the wheels
• D. Increased on all the wheels

Hint:

Gyroscopic forces and centrifugal forces interact to modify the distribution of load on the wheels of a vehicle, especially when negotiating curves. The outer wheels experience increased load, and the inner wheels experience decreased load.

Answer 1

The Correct Option is B

Step 1: Understand the forces involved in the problem
When a vehicle negotiates a curve, there are two primary forces acting on the vehicle: Centrifugal force: This force pushes the vehicle outward, away from the center of the curve.
Gyroscopic couple: If the vehicle has rotating wheels or other rotating parts, the gyroscopic effect can cause a tilting of the vehicle, which affects the distribution of forces on the wheels.
Step 2: Effect of centrifugal force
The centrifugal force causes the vehicle to push outward, increasing the load on the outer wheels and decreasing the load on the inner wheels.
Step 3: Effect of the gyroscopic couple
The gyroscopic couple works by tilting the vehicle. This tilt further exacerbates the effect of centrifugal force, increasing the load on the outer wheels while decreasing the load on the inner wheels.
Step 4: Conclusion
The total reaction on the ground, therefore, increases on the outer wheels and decreases on the inner wheels while negotiating the curve due to the combined effect of the centrifugal force and gyroscopic couple.
