Textbook Question
Chapter 3, Problem 57P
You’re designing a “cloverleaf” highway interchange. Vehicles will exit the highway and slow to a constant 70 km/h before negotiating a circular turn. If a vehicle’s acceleration is not to exceed 0.40g (i.e., 40% of Earth’s gravitational acceleration), then what’s the minimum radius for the turn? Assume the road is flat, not banked (more on this in Chapter 5).
