Step 1: Determine total height. The lamppost must be between 4 m and 6 m tall. Choose h = 5 m total height. h = 5 \, m Step 2: Design the pole. Pole height = 4 m (leaves 1 m for arm and light). h_pole = 4 \, m Step 3: Design the base. Use regular hexagon (n=6 sides). Side length s = 0.4 m. Perimeter P = n × s. P = 6 × 0.4 = 2.4 \, m Step 4: Design the arm. Arm has 3 bends (4 straight sections), total arm length 0.8 m. Each section l_section = 0.2 m. l_section = (0.8)/(4) = 0.2 \, m Step 5: Design the light. Sphere with diameter d = 0.2 m, radius r = 0.1 m. r = (0.2)/(2) = 0.1 \, m Step 6: Apply scale for drawing (1 cm = 1 m). Pole drawing height: 4 cm. Total height drawing: 5 cm. Base side drawing: 0.4 cm. Arm section drawing: 0.2 cm. Light diameter drawing: 0.2 cm. Final design summary: Total height 5 m, base perimeter 2.4 m, scale 1 cm = 1 m. 5 m
