Click on Beam View button above to start the program and adjust the frame to desired size by clicking and dragging on the edge of the frame.
Pay attention to how shear and moment distribution changes under each
load added to the beam keeping in mind that the slope of the moment diagram
at any point is equal to the shear at that section and the slope of the
shear is equal to the load density at that section.
You can choose from 4 types of beams.
Also there are 3 kind of loading to choose from.
In case of Linearly Distributed Load, the load density
varies from left end load density (w1) to right end load density
(w2), from the start point (a) to the end point (b) which
are measured from the left end of the Beam. The unit of load density is
When applying uniform load, put same value for w1 and w2 input fields.
When applying triangular load, put zero for one of w1 or w2 and the maximum for the other.
Linearly Distributed Load can be put in by Table Input in Option of the Menu bar. In each line, first put in the location of the point measured from the left and next the load density of that section separated by space, tab, or comma and press enter for each line. Press ADD button to add these loading to the beam.
After each load is added, this load will be shown in black color around the beam diagram with previously added loads. The total sum of the distributed load is shown on the top of the frame.
For the properties of the beam, there are input fields for the length
of the Beam (L), Young's modulus (E), and moment inertia
(I). When the values of these fields are changed and the add or initialize
button is pressed, the program will be initialized. This program assumes
constant cross section properties over the whole length of the beam.
The exaggerated deflection of the beam is displayed in blue line over
the beam diagram. The scale of the deflection line is set after initialization
or the boundary of the diagram is reached and then the deflection line
shows the relative change under added loads.
The scale of the deflection diagram relative to the length of the beam is shown on the bottom of the panel.
The shear diagram V, and the moment diagram M are shown under the beam diagram. The sign conventions are shown in the help of the program.
The reaction forces and moments are shown in red color. The calculated value of reactions are in red colored text under the moment diagram.
When the mouse is clicked over the diagram, the location, shear, moment and deflection of that section of the beam will be displayed in blue color text under the moment diagram.
Table output window shows current results for shear, moment, and deflections.
