How to Use the Moment & Shear Diagram Calculator
Using this calculator is simple and does not require advanced engineering software knowledge. Follow the steps below:
Step 1: Enter Span Length (L)
Input the total length of the beam in meters. This is the distance between the two supports.
Step 2: Add Uniformly Distributed Load (UDL)
Enter the load applied evenly across the beam in kN/m. This represents continuous weight distribution.
Step 3: Enter Point Load
Add the concentrated load acting on the beam in kilonewtons (kN).
Step 4: Define Point Load Position
Specify where the point load is applied along the beam length in meters.
Step 5: Click Calculate
Press the Calculate button to start the analysis process.
Step 6: Wait for Processing
The tool simulates calculation progress and processes structural results.
Step 7: View Results
You will see:
- Reaction at left support (RA)
- Reaction at right support (RB)
- Maximum Shear Force
- Maximum Bending Moment
Step 8: Copy or Share Results
You can copy the results for reports or share them with colleagues.
Practical Example of Beam Calculation
Let’s understand how this tool works in a real-world scenario.
Given Data:
- Span Length (L): 10 m
- UDL: 5 kN/m
- Point Load: 10 kN
- Point Load Position: 5 m
Step-by-Step Outcome:
After calculation, the tool provides:
- Reaction RA: 32.50 kN
- Reaction RB: 32.50 kN
- Maximum Shear Force: 32.50 kN
- Maximum Bending Moment: Approx. 81.25 kNm
Interpretation:
This means the beam is evenly supported, and the maximum stress occurs near the midpoint due to combined loading effects.
