For what value of \(\theta\) are the forces in the diagram above in equilibrium
Attached Figure / Diagram
A
\( 15^{\circ} \)
B
\( 30^{\circ} \)
C
\( 45^{\circ} \)
D
\( 60^{\circ} \)
Verified Correct Answer: D.
Physical Principles & Numerical Solution
So the diagram in the question is compressed to the one above.
From the diagram: Cos\(\theta\) = \(\frac{6}{12}\) = \(\frac{1}{2}\)
\(\theta\) = Cos\(^{-1}\)(0.5) = 60º
