    Given data:
    - Load applied: 30 kN (vertically downward)
    - Cantilever span: 5 m
    - Elastic modulus: 30 GPa
    - Section width: 0.3 m
    - Section depth: 0.6 m

    To find:
    - Elastic deflection of the cantilever

    Assumptions:
    - The cantilever is made of a homogeneous and isotropic material.
    - The load is applied at the free end of the cantilever.
    - The cantilever is subjected to pure bending.

    Formula:
    The formula for calculating the elastic deflection of a cantilever under pure bending is given by:
    δ = (FL^3) / (3EI)

    Where:
    δ = Elastic deflection
    F = Load applied
    L = Span of the cantilever
    E = Elastic modulus of the material
    I = Moment of inertia of the section

    Step 1: Calculate the moment of inertia (I):
    The moment of inertia (I) for a rectangular section is given by:
    I = (b * d^3) / 12

    Where:
    b = Width of the section
    d = Depth of the section

    Substituting the given values:
    I = (0.3 * 0.6^3) / 12
    I = 0.0216 m^4

    Step 2: Convert the load to N:
    The given load is in kN, so we need to convert it to N:
    Load (F) = 30 kN = 30,000 N

    Step 3: Calculate the elastic deflection (δ):
    Using the formula:
    δ = (FL^3) / (3EI)

    Substituting the given values:
    δ = (30,000 * 5^3) / (3 * 30 * 10^9 * 0.0216)
    δ ≈ 7.7 mm

    Conclusion:
    The elastic deflection of the cantilever is approximately 7.7 mm. Therefore, the correct answer lies between 7.65 mm and 7.75 mm.
