    The Beams program will compute the deflections and the stresses in five
    types of constant  cross-section beams.  When the program  asks for the
    type of beam, press a number key 1 through 5.

    1 - Simple support at two points.
    2 - Simple support at three points.
    3 - Fixed support at one end.  (Cantilever)
    4 - Fixed support at one end and a simple support at the other end.
    5 - Fixed support at both ends.

    You may select one of three types of loads.  Press 1 through 3.

    1 - Uniform load on the entire length of the beam.
    2 - Load at one point on the beam.
    3 - Load at two points on the beam.

    Note: You may not have Beam type 2, simple support at three points and
          and Load type 2,  load at  one  point.   You may get around this
          restriction by selecting Load type 3 and making one of the loads
          a small number.

    All lengths  are measured  from the same  end and  are in  inches.  All
    loads are  in pounds.  The  input values  may be numbers,  variables or
    expressions and you may  use the cursor keys, Ins and  Del to edit your
    input data. (See help screens to Calculator.)

    The  program  must  know  the modulus  of  elasticity  for  the  beam's
    material.  The default  modulus of elasticity is 30  million for steel.
    If this is  the proper value you  may just press "Enter"  to accept it.
    Another common  value for the modulus  of elasticity is 29  million for
    structural steel.   To select  this value  just press  the letter  "S".
    Otherwise type the  value required and press "Enter".   For example you
    may select Aluminum  as your material.  Upon looking up  the modulus of
    elasticity in  tension for  aluminum in  your handbook  you may  find a
    value of  10.3 million.  Therefor  you must  key in 10300000  and press
    "Enter".

    Next you must  enter the moment of  inertia and the section  modulus of
    the cross-section  of the beam.   If the  cross-section of the  beam is
    circular such as a shaft or tube you may press the letter "S" for shaft
    and the  program will calculate the  moment of inertia and  the section
    modulus after asking for the diameters of the beam.  Otherwise you need
    to look  in your handbook  for the values  or the formulas.   Let's say
    your beam is  an 8 inch high by 23  pound per foot I beam, (S  8 X 23).
    Looking in your  handbook you will find  the moment of inertia  is 64.9
    and the section modulus is 16.2.  You  will type 64.9 and press "Enter"
    and then when the  prompted for the section modulus you  will enter the
    16.2.

    For a second case lets say your beam  is a rectangle that is 3.5 inches
    high and  0.5 inches wide.   Looking in your  manual you will  find the
    formula for the moment of inertia  is "width times height cubed divided
    by 12",  w*h^3/12.  So for the moment of inertia you would key in:

    .5 * 3.5 ^ 3 / 12 <Enter>

    The formula  for the  section modulus  is "width  times height  squared
    divided by 6", so you would key in:

    .5 * 3.5 ^ 2 / 6 <Enter>

    You will be prompted for the lengths  to the loads and the supports and
    the loads themselves.

    When all of the  data has been entered you will get  a list of stresses
    and deflections  at critical locations.  If  you would like  the stress
    and deflection  at a point that  is not on  the list you may  enter the
    length of  interest and the  program will  compute the values  for that
    point.  If  you want  to change any  input values at  any time  you can
    press the letter "R" for repeat.  Press "Esc" to quit.
