How does a lever allow a weight to be lifted that is too heavy to be lifted without a lever?

To understand the lever you have to understand the concept of work. (That's work as it is defined in the physically sciences, not the social responsibility which seems to be far more difficult to understand).
Acceleration is how much an object of capable of being sped up. It is measure in meters per second squared. m/s2
Force is what accelerates a mass. It is measured in Newtons, or Kilograms meters per second squared. Kg m/s2
Energy is what you have when you apply a force through a distance. It is measured in Joules, or Kilogram meters squared per second squared. Kg m2/s2
No when you have a lever you have a long end and a short end. The long end is high, the short end is low. The weight to be lifted is on the short end, your effort is being applied to the long end.
Your effort is applied to the entire distance that the long end travels from high to low (it is a great distance). Your effort is also applied to the entire distance that the short end travels for low to high (it is a small distance).
Now each end of the lever has the same amount of energy, (but the distances traveled are different) so the only way that the energy can be equal is that the FORCE at either end is also different - and different in such a way that it balances the energy at either end. The only way that this can happen is that the 'force on the short end' is greater than the 'force on the long end'.
F1d1 = F2d2 but d1>>d2 so F2 has to be much greater than F1

When you do bicep curls and tricep dips does it burn fat from your arms aswell as tone them?
In order to tone your arms you need to do more reps and try not to go so heavy on the weight unless you're trying to bulk up. Heavier weight will make your arms larger without a lot of definition, while lighter weight will give you the definition without the bulk. To get a nice lean look in your arms try doing heavy weight with more sets and less reps one week and less weight and more reps on the other. be sure to allow an ample amount of time to allow your muscles to heal otherwise what you have worked on will have been a waste of time.
