- - - - A lever is a rigid bar that is supported by a fulcrum.
      - • F is the force or effort appbed at one end of the bar.
      - • R i s the resistance or load which acts at the other end of the bar.
      - • d i s the distance from F to the fulcrum
      - • r is the distance from R to the fulcrum
  - - - A fixed pulley is balanced when the effort F is equal to the resistance of the
      - load, R:
      - F = R
  - - - A moveable pulley is balanced when it satisfies this equation
      - F=R/2
- - - - The first wheel is called the primary drive wheeL When it moves, i
        turns or drives the second or output wheel, causing it to move as well.
    - - Their axles are parallel and they rotate simultaneously due to the effect
        of the belt.
  - - - N, Z ,=N ,.Z,
  - - - To calculate the ratio between the rotation velocity of the drive wheel cogwheel 1
        (I) and the driven wheel (2), use the same formula as for gear mechanisms
