Question
The steering wheel of a vehicle is of large diameter.
Advertisements
Solution
The larger the radius the greater the torque. Another way of stating that is that a smaller force on a large wheel could generate the same torque as greater force on a smaller wheel. Hence, the steering wheel of heavy vehicles has a large diameter.
