Homework Help: Truck Incline FBD

  1. Jun 2, 2010 #1
    1. The problem statement, all variables and given/known data

    I want to know if I drew this free body diagram correctly.

    Information about the problem:
    1:The truck has a load which is the black park as it goes up the incline. It doesn't have a load when it goes down the hill.
    2:The truck is rear wheel driven.
    3:The truck has regenerative breaking used when it goes back down the hill.
    4:The wheels do not slip.
    5: This assignment is just identifying only the external forces on the truck.

    2. Relevant equations

    1: Did I draw the Force going uphill in the right area? I put it on the rear wheel since it's rear wheel drive. However, I feel like it just might go in front of the car.
    2: The front breaks have regenerative breaking when the car is going downhill. What type of force is acting on the front wheel? And how does it effect the rest of the car ?
    3: And in general did I draw all the forces correctly?
