Question

The curved section of a horizontal highway is a circular unbanked arc of radius 550 m. If the coefficient of static friction between this roadway and typical tires is 0.30, what would be the maximum safe driving speed for this horizontal curved section of highway?

Answer 1

The value is
`v = 40.20 \ m/s`

Step-by-step explanation:

From the question we are told that

The radius is
`r = 550 \ m`

The coefficient of static friction is
`\mu = 0.30`

Generally the maximum safe driving speed is mathematically represented as

`v = √(\mu * r * g )`

=>
`v = √( 0.30 * 550 * 9.8 )`

=>
`v = 40.20 \ m/s`
