📘 Calculation of the Moment of Inertia for a Rectangular Section 🧩 Project Description

This program was developed to calculate fundamental geometric properties of a beam with a rectangular cross-section, commonly used in Structural and Mechanical Engineering. The application reads the beam’s dimensions (width and height), computes the cross-sectional area and the moment of inertia about the neutral axis, and displays the results in a clear and interpretable way.

⚙️ Features

Reads the width (b) and height (h) of the beam (in centimeters).

Calculates the cross-sectional area:

𝐴

𝑏 × ℎ A=b×h

Calculates the moment of inertia about the neutral axis:

𝐼

𝑏 × ℎ 3 12 I= 12 b×h 3 ​

Checks whether the area is greater than or equal to 100 cm², indicating if the beam can support a “basic load.”

Displays the calculated results neatly formatted.

🧮 Example Output Enter the width (b) in cm: 10 Enter the height (h) in cm: 15

Cross-sectional Area: 150.00 cm² Moment of Inertia: 28125.00 cm⁴ The beam is suitable to support the basic load.
