Statics on Car Wheel

  1. Dec 11, 2016 #1
    1. The problem statement, all variables and given/known data
    http://imgur.com/a/IYbP1
    A Car sitting on a frame with an attached bar pressing down on the hinged section (Orange). A hinged section coming off the frame with a wheel attached (Blue)

    How to calculate the radial force on the wheel bearing at 1m away from centre of engine?

    2. Relevant equations
    Statics, sum of the directions.

    3. The attempt at a solution
    I have split the engine weight into 2 and multiplied by the distance 1m to get 250kg.m

    If I multiply 250kg by 9.81N I get 2.452kN of force.
    I'm negating the bar pushing down because that will be set equal to the Fxd at that location, so I can ignore that for the wheel location?

    How is 250kgm equal to 250kg even though it's 1m away? How do I convert this properly to get a force?

    Can you explain why you calculated the torque? The torque would be trying to bend the frame and would be resisted by equal internal forces.

    How about drawing a free body diagram just showing all the external forces?
