4B. Apply External Loads
Depending on
what type of problem you are trying to solve, you should now apply the loads
to your part whether they be forces, pressures, temperatures, electric potentials,
etc. Since this beam is to be subjected to 4 point bending, equal concentrated
loads should be applied to the beam at x =8in and x = 16 in.

APPLY -> Force/Moment
FORCE/MOMENT -> On Lines
ANSYS GRAPHICS WINDOW -> With the left mouse button, select
the nodes at the top of the beam and at x = 8in. and x = 16in. Then click
APPLY in the APPLY F/M ON NODES window.
APPLY F/M ON NODES -> For "Direction of Force/Moment" Choose
FY
APPLY F/M ON NODES -> For "Force/Moment value" enter the
load in pounds. For this example enter -1000.
It is negative so that the forces are pointing downward.
APPLY F/M ON NODES -> Click OK
Two arrows should appear on the beam as shown in the figure below.
NOTE: These arrows will appear at the bottom of the beam despite picking the
points on the top of the beam.
