The mass center of the rear-engine 3450-lb car is at G. Determine the normal forces N and NB exerted by the road on the front and rear pairs of tires for the conditions of (a) being stationary and (b) braking from a forward velocity v with all wheels locked. The coefficient of kinetic friction is 0.88 at all tire/road interfaces. Express all answers in terms of pounds and as percentages of the vehicle weight. Go 21" B 65" 48" Answers: (a) While stationary: NA = i lb = i % of the total weight NB = i lb = i % of the total weight (b) While braking: NA = i NB = i lb = i % of the total weight lb = i % of the total weight Q Search N W
