Deflection Formula:
From: | To: |
The deflection formula calculates the maximum deflection of an angle iron beam under a uniformly distributed load. This is important for structural engineering applications to ensure beams don't deflect beyond acceptable limits.
The calculator uses the deflection formula:
Where:
Explanation: This formula calculates the maximum deflection at the center of a simply supported beam carrying a uniformly distributed load.
Details: Calculating deflection is crucial in structural design to ensure that beams and other structural elements don't deform excessively under load, which could lead to serviceability issues or structural failure.
Tips: Enter all values in the specified units. Ensure all values are positive and within reasonable ranges for accurate results.
Q1: What is the weak axis moment of inertia?
A: The weak axis moment of inertia (I_weak) is the second moment of area about the axis with the smallest resistance to bending.
Q2: When is this deflection formula applicable?
A: This formula applies to simply supported beams with uniformly distributed loads and linear elastic material behavior.
Q3: What are typical values for modulus of elasticity?
A: For steel, E is typically around 200 GPa (200 × 10⁹ Pa). For aluminum, it's about 69 GPa (69 × 10⁹ Pa).
Q4: How does length affect deflection?
A: Deflection increases with the fourth power of length, making longer beams much more susceptible to deflection.
Q5: What are acceptable deflection limits?
A: Acceptable deflection limits vary by application but are often specified as a fraction of the span length (e.g., L/360 for floors).
