Question 62
XE-CNAT2 marksNeeds review
At the peak (also denoted as UTS) of an engineering stress vs. engineering strain curve for ductile metal, the engineering strain is 0.2. The corresponding true stress (σ) vs. true strain (ε) relationship follows the equation: σ = Kεⁿ, where K and n are constants.
The engineering stress at the peak, in MPa, is ________ (rounded off to one decimal place).
Given: K = 200 MPa
