Elastic Beam Deflection Calculator

Please enter in the applicable properties and values to be used in the calculation.
IMPORTANT: UNITS MUST REMAIN CONSISTENT THROUGHOUT ALL VALUES.
Once all values are entered, select the image that most resembles the situation of concern and click the "Submit for Calculation" button for results.

NOTE: If the situation consists of several loads on the beam, remember the superposition principal: simply enter in the 'component' situations and sum up the deflection.
