A steel rod 55 cm long has a diameter of 30 cm. The compressive strength (the maximum stress it can support without breaking) of this steel is 500 × 10⁶N/m². What is the compression force that would break the rod? A) 3.5 × 10⁷ N B) 2.4 × 10⁷ N C) 1.4 × 10⁸ N D) 4.7 × 10⁸ N E) 8.9 × 10⁸ N

The area of the rod is:A = πr^2 = π(0.15 m)^2 = 0.0707 m^2The compression force is:F = σA = (500 × 10^6 N/m^2)(0.0707 m^2) = 3.5 × 10^7 N
