Calculate the maximum deflection of the following beam in millimetres (mm). Assume the beam is made of steel with E = 200 000 MPa

Please write your answer to 2 decimal places, do not include units in your answer and consider a downwards deflection to be positive.

The formula for the deflection at the mid-span of a simply supported beam is δ = 5wL⁴/384EI where a positive deflection here indicates a downwards deflection.
