Machine: A machine is a set of moving parts and non-mobile, that the effect of its links are capable of transforming energy.
simple machine: A simple machine is a device that only requires the application of force to operate.
Mechanism: in mechanical mechanism is called a set of rigid elements, moving from one another, whose purpose is the transmission of motion and strength.
Lever Act: The product of his arm strength is equal to the strength of his:
FxBf = RxBr
elements involved in this act:
R: Resistance
r: resistance arm
F: Force
f: arm strength
Problem: A lever has arm force 2 m resistance arm 4 m. If want lift a weight (or Resistencia) 100 Kg What force'll do?
F * f = R * r
F * 2 = 100 * 4
F = 400 / 2
F = 200
