Solución

Respuesta: β = 2,4 × 10^−5 K^−1 (que corresponde a α ≈ 1,2×10^−5 K^−1). To master the concept of Superficial Dilatation (thermal

Primero, calculemos el cambio en la temperatura:

• Initial hole radius (r_0 = 5 , cm = 0.05 , m)
• (A_0 = \pi r_0^2 = \pi (0.05)^2 = 0.007854 , m^2)
• (\beta = 2\alpha = 3.8 \times 10^-5)
• (\Delta T = 180 , \text°C)
• (\Delta A = 0.007854 \times 3.8 \times 10^-5 \times 180)
• (\Delta A \approx 5.37 \times 10^-5 , m^2)
• (A_f \approx 0.007908 , m^2) (or (79.08 , cm^2))
