16.4. Curve Resistance

Try these first

1. 1.

   What does curve resistance refer to?

   Hint

   Think about the difference in how the front and rear wheels behave.

2. 2.

   What is the definition of tractive force?

   Hint

   It relates to movement and pushing forward.

3. 3.

   What is the formula for calculating curve resistance (CR)?

   Hint

   Focus on the relationship between forces.

4. 4.

   True or False: The rear wheels generally turn more than the front wheels in a curve.

   Hint

   Think about the mechanics of how vehicles turn.

5. 5.

   A vehicle with a total tractive force of 1200 N experiences a steering angle of 45 degrees. Calculate the curve resistance and discuss how it affects vehicle handling.

   Hint

   Focus on the cosine function for angle conversion.

6. 6.

   Discuss the implications of designing a road with a tight radius of 30 meters and how curve resistance might influence vehicle safety.

   Hint

   Consider the relationship between radius, speed, and forces acting on the vehicle.
