How to use the Simply Supported Center Load Deflection Calculator
Calculate center deflection PL³/(48EI).
What the inputs mean
- Center load (N)
- Enter the value requested by this field label.
- Span (m)
- Enter the value requested by this field label.
- Elastic modulus (Pa)
- Enter the value requested by this field label.
- Second moment (m⁴)
- Enter the value requested by this field label.
Formula or calculation method
The calculator applies the standard mathematical relationship for the labeled inputs and returns the computed result automatically.
Example
Try entering realistic values for Center load (N) and Span (m), then tap Calculate to see how the result changes.
How to understand the result
Use the result as an estimate based on the values you entered. For planning decisions, double-check that the input units and assumptions match your real situation.
Tip: Keep all values in compatible units and use values from the same time period when the calculator compares two amounts.
