# If you wish to reduce the stress (which is related to centripetal force) on high-speed tires, would you use large- or small-diameter tires? Explain.

Centripetal is the force that acted on a body in a circle always the effective inward direction of the circular path.

See the step by step solution

## Step 1: Definition of Centripetal Force

The centripetal force causes a body to follow a curved path. It always moves in the opposite direction of the body, towards the fixed point of the path's instantaneous centre of curvature.

Centripetal Force

${\mathbf{F}}_{\mathbf{c}\mathbf{}}\mathbf{=}\frac{{\mathbf{mv}}^{\mathbf{2}}}{\mathbf{r}}$

Where

$\mathbit{r}$ =Radius

$\mathbit{m}$ = Mass

$\mathbit{v}$ =Velocity

On increasing the radius, the centripetal force (Stress) would decrease .Therefore; more diameters would cause the less stress.

## Step 2: Determine how large diameter tier not to slide off the road

If we reduce the stress on high speed tier, there should be use of large diameter tire as it has more friction so that it would not slide off the road.
