I think Macrobe meant to ask how much force would be required to get a body off its stationary position. On a flat surface, it is equal to the co-efficient of static friction x Weight of the body (weight, not mass). If the body is on, say, a road, the force required to get the body would be...

Ah, bending the rules are they? :cool:

Yes, the start is important, but I believe they would have a built-in heater only if it's going to be of use throughout the race. If it's simply for the start, they might as well adopt an external method. I'm sure that using heating ovens for this is illegal, but I'm not sure about what other...

Having known the result, I guess we can reason out to an extent why the unit involves the product of pressure (which is basically force on a unit area) and time. We can get a measure of the thickness of the fluid by studying its reaction to an applied force. If I apply a greater force, I will...

I also think that an effort to keep the tyres warm is required only at the start of the race when the tyres may be, to an extent, cold. Once the race beings, the drivers start burning (sometimes literally!) the tyres with their speed. On the rare occasions when they do tone down their speed...

I'm sorry, I didn't notice the fact that the springs were precompressed.

I don't quite agree that the left hand spring is assisting the motion. It is in fact opposing it. Just think of it, it would certainly be easier to displace the body if that spring weren't there. As far as why they're considered to be in parallel, you can see it from the math if you don't feel...

The steering knuckle is usually connected to one side of the centre of the wheel to make the wheel turn. Adjusting it such that it connects to the other side of the centre could help you achieve this, although I'm not sure how accurately. Watching this video might give you a better idea of...

Alright, I get it now. Thanks a lot!

Thanks for the reply. But just like a ball bouncing off the wall, why can't the first ball in the cradle retain some energy and bounce back, passing on the remaining energy to the next ball, hence conserving energy?

Hello everyone! I was just reading about the working of Newton's Cradles and ended up having some confusion. When a ball is taken to a certain height and dropped, it comes down and hits the next ball. Now the explanation as to why the first ball stops and doesn't bounce back is attributed...
