Unformatted text preview: ME 131 Vehicle Dynamics Homework 6 Solutions 1 Term Project Proposal Submit a 1-page proposal outlining your planned term project. This proposal will not be graded but will be used to determine if the project is acceptable. Outline your objectives and how you will go about meeting them. If it is a group project outline what you specifically will be doing on the project. 2 Lateral and Longitudinal Dynamics (a) In racing, beginners are often taught to finish braking before they start turning the wheel. Why is this? Is this optimal? Explain using the friction circle. (1 pt) This is to prevent overloading the tires by braking and turning at the same time (they should show an illustration of the friction circle to demonstrate this). This is not optimal, the optimal solution would be to drive on the edge of the friction circle at all times. (b) If you are cornering at the limit of the vehicle, how many tires are ”saturated” (at the edge of the friction circle)? Which tires are saturated? Note: This may depend on whether the vehicle naturally oversteers or understeers. (3 pts) If the car is truly neutral, all 4 tires will saturate simultaneously. If the vehicle understeers the twoIf the car is truly neutral, all 4 tires will saturate simultaneously....
