How do you calculate the deflection of a cantilever beam in structural engineering?

The deflection of a cantilever beam in structural engineering can be calculated using the following equation:

δ = (5WL^4)/(384EI)

where:

δ = deflection
W = load applied at the free end of the beam
L = length of the beam
E = modulus of elasticity
I = moment of inertia of the beam's cross-sectional area

Once the values of W, L, E, and I are known, the deflection of the cantilever beam can be easily calculated using this formula.
