Correct.
No. The hypotenuse is larger than the other sides of the triangle. How can a component be greater than the whole?

It's possible you are confusing the mechanical geometry (where the con rod does look like the hypotenuse) with a vector component diagram where it isn't.

Consider this diagram..

I have marked a vector Fp and shown it's components in the X and Y directions. Does that make sense?

That makes sense now entirely! I see, thank you for all your help :) is there a way I can give you rep or something on this forum?
