Instructions for using the Calculator
This free online calculator is developed to
calculate the slope and
deflection at any point of the cantilever beam carrying
point load, moment, uniform load (udl) or varying load (udl).
It also gives the values of maximum slope and deflection which occur
at the free end.
(i) The forces and deflection
upward are considered as positive and counter clock-wise moment and
taken as positive.
(ii) Take the origin of reference axes at the extreme left end of the
beam. All the distances should be entered in meter and load in kN,
Moment of Inertia in cm4 and Modulus of
elasticity (E) in GPa. It will give the values of slope (in
rad.) and deflection (in mm) at any section of cantilever.
(iii) You can also quickly get the deflection values
at different points of the beam just by changing the position of
section "x" (taking origin of axes at left support)
(iiv) This calculator will also help you in getting the
ordinates of influence line diagram for deflection in case of moving load on the
In case of combination of loads, you can apply the principle of
superposition to calculate the resultant slope and deflection.
