FUNCTION calculate_concrete_volume(length, width, depth)

  # Calculate the area of the floor slab
  area = length * width

  # Calculate the volume of concrete required

# Constants
M = 140  # Moment at the cross-section (kN.m)
I = 102_000_000  # Moment of inertia in mm^4
y = np.array([-150, -100, -50, 0, 50, 100, 150])  # Distance from the neutral axis in mm

# Bending stress calculation
sigma = ((M * 1e6) * y) / I  # Convert M from kN.m to N.mm

def plot_beam_diagrams(length, w):
    """
    Plot the shear force and bending moment diagrams for a simply supported beam.

    Parameters:
    - length: Length of the beam (m)
    - w: Magnitude of the uniformly distributed load (kN/m)
