**Problem 2 – Compression Testing**

A compressive test is performed on a specimen of hot-rolled and annealed stainless steel alloy 304 (304 SS). Its rectangular cross section is initially 11 mm wide and 6.2 mm thick. When a compressive force (Fₓ) of -11798.6 N is applied, the resulting instantaneous gauge length (lᵢ) is 49.9552 mm.

A. What is the applied, instantaneous, engineering compressive stress (σₓ) in MPa?
B. What is the original gauge length (lₒ) in mm?
C. What are the deformation elongations in the lateral (cross-section) plane (Δwᵢ and Δtᵢ) in mm?
D. What is the Modulus of Resilience (Uᵩ) when Fₓ is applied, in J/m³?
E. What are the original and deformed volumes of the gauge length in mm³?

All six sections of the solution are needed.
