I emailed them and they said they had no idea if it would fit.Bent bolt? I hope there was no damage to the vehicle. The only thing about the MSource bolt is that they do not mention that it fits w210 (it seems like it does not).
If it was three feet long, and you placed the jack at the end farthest away from the car, then, in all likelihood, the jacking point would twist up as you tried to lift the car because it is indeed nothing but one mother of a lever.I do not see why it would matter if the bolt was 3 feet long as long as it did not bend. It is not a lever, the jack lifts the load.
The fulcrum is the top of the outer edge of the jacking point hole...this is a lever. If the bar was welded to the jack such that it could only go up whilst maintaining a horizontal aspect then yes, but it isn't, so it's a lever.No fulcrum - no lever.
Um, it is indeed a lever. It may not be doing the lifting, but it is doing the *supporting* and you are transferring a significant load to the bolt shaft. Hold a bowling ball next to your body, then hold your arm straight out. It's the same mass, but the load increases.I do not see why it would matter if the bolt was 3 feet long as long as it did not bend. It is not a lever, the jack lifts the load.
That again depends how far you set the jack off the car jacking hole.Three only question is, how hard a bolt would I need to use one of the rear lift points to raise the entire side of the car?![]()
I agree, but make it a 10inch dowel and it will break. Thus the argument about not being a lever is...suspect.That again depends how far you set the jack off the car jacking hole.
I am pretty confident that if you can put jack right next to the hole -even wood dovel would support the car weight.
But that might be impossible to set in real life.
Probably doesn't matter how you describe it. If it doesn't look like the drawing with a big rock, a long stick and a small rock underneath the stick, you'll not convince them.Boy, am I glad I took physics.![]()
Good idea.Probably doesn't matter how you describe it. If it doesn't look like the drawing with a big rock, a long stick and a small rock underneath the stick, you'll not convince them.![]()
Actually it does, but you have to reverse the image in your head. Think about the edge of lifting hole as as small rock (upside down) and the force at the end of the lifting rod under the floor as a big rock.Probably doesn't matter how you describe it. If it doesn't look like the drawing with a big rock, a long stick and a small rock underneath the stick, you'll not convince them.![]()
Let's agree to disagree.Good idea.

So if this is a Class 2 lever and the diagram of the rocks is representative then the max effort force at the jack hole to lift both tires on the same side off the ground would be 1950 lb. And that makes sense at that is 1/2 the weight of 2000 w210 E320.
Using the 9 inch bolt the force will be about 125 lb less as the jacking point. If you can find that 3 foot long bolt the effort force required at the jack will be only 1220 lbs.
It is going to take a rod about 75 feet long before I can lift it myself, but I think the force at the jack hole is the same no matter what:
