The wheelbase on a 50,000-kg truck is 2.40 m wide and the truck's center of mass is located along the vertical centerline of the truck and 2.00 m above the bottom of the tires. The truck is going around a horizontal turn with a radius of 250 m at 24.0 m/s. What is the total normal force on the tires on the side of the truck that faces the center of the curve?
A) 245 kN
B) 149 kN
C) 349 kN
D) 283 kN
E) 255 kN

The centripetal force causes a shift in the normal force distribution. The normal force on the inner tires is reduced due to the lateral acceleration. Calculating the lateral force and using torque balance, the normal force on the inner tires is found to be approximately 149 kN.
