Car Wheel Statics: Calculating Radial Force at 1m

AI Thread Summary
The discussion focuses on calculating the radial force on a car wheel bearing located 1 meter from the engine's center. The user has attempted to determine the force by splitting the engine weight and calculating torque, resulting in a force of 2.452 kN. There is confusion regarding the conversion of torque to force and the relevance of the downward force from the bar. Participants suggest using a free body diagram to visualize external forces acting on the system. Clarifying these concepts is essential for accurate calculations in statics.

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?

Homework Equations


Statics, sum of the directions.

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?
