📘 Python for Civil Engineering – Module 1: Basics

# Module 1: Python Foundations for Engineers

This notebook covers:
1. Factor of Safety (FoS)
2. BMI Calculator
3. Simple Interest
4. Material Quantity Estimation (Loop Example)

---

🔹 1. Factor of Safety

# Factor of Safety Calculation

def factor_of_safety(strength, stress):
    if stress == 0:
        return "Stress cannot be zero!"
    return strength / stress

# Example usage
strength = float(input("Enter material strength (N/mm²): "))
stress = float(input("Enter applied stress (N/mm²): "))

fos = factor_of_safety(strength, stress)
print(f"Factor of Safety = {fos:.2f}")

if isinstance(fos, float):
    if fos >= 1.5:
        print("✅ Safe design")
    else:
        print("⚠️ Not safe, redesign required")

🔹 2. BMI Calculator (Worker Health Check)

# BMI Calculation

def bmi(weight, height):
    return weight / (height ** 2)

weight = float(input("Enter weight (kg): "))
height = float(input("Enter height (m): "))

bmi_value = bmi(weight, height)
print(f"BMI = {bmi_value:.2f}")

if bmi_value < 18.5:
    print("Underweight ❗")
elif 18.5 <= bmi_value < 24.9:
    print("Normal ✅")
elif 25 <= bmi_value < 29.9:
    print("Overweight ⚠️")
else:
    print("Obese 🚨")

🔹 3. Simple Interest (Finance in Construction Projects)

# Simple Interest Calculator

def simple_interest(principal, rate, time):
    return (principal * rate * time) / 100

p = float(input("Enter Principal Amount (₹): "))
r = float(input("Enter Rate of Interest (%): "))
t = float(input("Enter Time (years): "))

si = simple_interest(p, r, t)
print(f"Simple Interest = ₹{si:.2f}")
print(f"Total Amount Payable = ₹{p + si:.2f}")

---

🔹 4. Material Quantity Estimation (Loop Example)

# Calculate volume of multiple beams (loop example)

n = int(input("Enter number of beams: "))
total_volume = 0

for i in range(n):
    print(f"\nBeam {i+1}")
    length = float(input("  Enter length (m): "))
    breadth = float(input("  Enter breadth (m): "))
    depth = float(input("  Enter depth (m): "))
    
    volume = length * breadth * depth
    total_volume += volume
    print(f"  Volume = {volume:.2f} m³")

print(f"\nTotal Concrete Volume for {n} beams = {total_volume:.2f} m³")
