Engineers can also use empirical formula to quickly calculate the deflection of a beam which is what we'll use for the below example: Lets consider a simple supported beam with a span of a uniform load of w = 10 kN/m over a L = 10m span, and the following material properties: Youngs modulus, E = 200,000 MPa, and the moment of inertia about the y axis is I = 0.0015 m^4. . Since we need to calculate I, its moment of inertia would be: I = width height / 12 We call the amount of beam bending beam deflection. Now that we know the concepts of modulus of elasticity and moment of inertia, we can now understand why these variables are the denominators in our beam deflection formulas. Since we are considering the deflection of the beam when it bends vertically or around the x-axis, we have to use I for our computations.
