  87. In the 1st order lever, which is in the middle: folcrum, resitance, or effort.  Also give an example.
    In 1st order lever, the folcrum is in the middle.  An example is way the head balances on the spine.  The muscle gives the effort.
  88. In the 2nd order lever, which is in the middle: folcrum, resitance, or effort.  Also give an example.
    With 2nd order levers, resistance is in the middle.  An example is the madible. 
  89. In the 3rd order lever, which is in the middle: folcrum, resitance, or effort.  Also give an example.
