Force into a spindle

[baja B-rad]

Does any one know a good website or equations in general to find the force that is imputted into a front spindle given the speed of a vehicle and the size of bump it is hitting? My physics is a little rusty and my numbers are comming out huge. Any help would be greatly appreciated.

Force vectors. Use these to show what is happening to the wheel and spindle on paper. After you have your force vectors in place and have taken as accurate measurements as you possibly can you can do the simple math to get a load rating in the form of a number. Have you had a Physics course before?

make a few assumptions as well...
No shock/spring aka rigid
No Tire deflection

Your numbers coming out huge doesn't appear unreasonable. If you had your force vectors pointing correctly, assumed rigid tire/shock, I bet that the numbers [I]would[I] be huge. Also if you had the entire weight of the truck coming down on only one spindle in your calculations...

First, I'd find some online example describing "if you dropped a bowling ball off the roof... neglecting wind resistance, how fast would it be going when it hit the ground?" That would cover F=ma (force equals mass times acceleration). Choose a distance, like 10 (meters are good), calculate acceleration due to gravity (9.8m/s^2), plug a bunch of stuff in and move things around and do some more math and possibly use another equation, but be careful not to divide by zero, and eventually I think you'll get to a big number. But its possible that acceleration becomes infinity (negative infinity) at the point of inpact, so clearly I have no idea.

I figured I was making it too complicated. Like I mentioned it has been a while since physics or dynamics. I had a problem with one of my numbers and it was making my answer go crazy. Thanks for everybodys help
