Explanation

(ii) Using Lami's theorem,

\(\frac{48}{\sin 150} = \frac{T}{\sin 120}\)

\(T = \frac{48 \sin 120}{\sin 150}\)

\(T = 83.14N\)

The tension in DB is 83.14N.

(iii) Using Lami's theorem,

\(\frac{10q}{\sin 90} = \frac{48}{\sin 150}\)

\(10q = \frac{48 \sin 90}{\sin 150}\)

\(10q = 96 \implies q = 9.6kg\)

Correct Answer: D. shearing
