In the marine crane shown, link \( C D \) is known to have a uniform cross section of \( 50 \times 150 \mathrm{~mm} \). For the loading shown, determine" the normal stress in the central portion of that link. HINTS: 1. \( \sigma=\frac{F}{A} \) 2. Draw freebody diagram. 3. Take moment abot \( A: \underbrace{-} \sum M_{A}=0 \) a. \( +195.3 \mathrm{MPa} \) b. \( +155.3 \mathrm{MPa} \) c \( +200.5 \mathrm{MPa} \) d. +188.3 MPa
