Medida del tubo: 15cm
La forma de graduar los ángulos es mediante un transportador ubicado en la parte derecha el cual
tiene una pequeña cuerda con peso la cual me indica el ángulo
Y el resorte funciona mediante un breve mecanismo el cual, dependiendo la presión ejercida
dentro del tubo, se va encajando en pequeños agujeros los cuales impiden El movimiento de un
resorte el cual puede ser liberado utilizando una cuerda

Create a 3D model of a combined ruler and protractor. Base: rectangle, 6×2 inches, 3 mm thick. Add imperial and metric measurement lines: inch marks 3 mm, half-inch 2.5 mm, quarter-inch 2 mm. Include raised numbers, 2 mm high, aligned with marks. Add a semicircle protractor at one end with degree marks every 10° and numbers every 30°, highlighting 45°, 90°, 180°. Include a 5 mm diameter hanging hole in a corner. Ensure all elements are grouped, aligned, and printable.

Now I will explain clearly, step-by-step, what you just saw and what you must physically make for your project.
No confusion. Just structured execution.

🔵 PART 1 — YOUR MODEL BASE (Physical Structure)
Step 1: Ground Construction
You are given:
R=40 cmR = 40 \text{ cm}R=40 cm
Full Ground Area
A=πR2A = \pi R^2A=πR2 A=3.1416×402A = 3.1416 \times 40^2A=3.1416×402 A=3.1416×1600A = 3.1416 \times 1600A=3.1416×1600 A=5026.55 cm2A = 5026.55 \text{ cm}^2A=5026.55 cm2
✔ This matches the calculated result.

Step 2: Divide Into 8 Equal Sectors
Since:
360∘÷8=45∘360^\circ ÷ 8 = 45^\circ360∘÷8=45∘
Each sector angle = 45°
Area of One Sector
Asector=45360×5026.55A_{sector} = \frac{45}{360} \times 5026.55Asector​=36045​×5026.55 =18×5026.55= \frac{1}{8} \times 5026.55=81​×5026.55 =628.32 cm2= 628.32 \text{ cm}^2=628.32 cm2
✔ This also matches the computed value.

🔵 PART 2 — Probability Data Used
We assumed this shot distribution:
Sector
Probability

S3
0.18
S4
0.10
S5
