QUESTION:
Repeat Prob. 5/149, where the 1500-N load has been replaced by the \(4.2-\mathrm{kN} \cdot \mathrm{m}\) couple.
ANSWER:
Step 1 of 7
Calculate the reactions.
\(\begin{array}{l}
A_{y}+B_{y}=800 \mathrm{~N} / \mathrm{m}(3 \mathrm{~m})=2400 \mathrm{~N} \\
\sum M_{A}=0 \\
B_{y}(2+3+2+2)=800 \times 3\left(\frac{3}{2}+2\right)+4200 \\
B_{y}=1400 \mathrm{~N} \\
A_{y}=2400 \mathrm{~N}-1400 \mathrm{~N} \\
A_{y}=1000 \mathrm{~N}
\end{array}\)
