Statics Jl Meriam 8th Edition Solutions: Engineering Mechanics

$\mathbf{M}_A = \begin{vmatrix} \mathbf{i} & \mathbf{j} & \mathbf{k} \ 0.2 & 0.1 & 0 \ 100 & 0 & 0 \end{vmatrix} = 0 \mathbf{i} + 0 \mathbf{j} -10 \mathbf{k}$

The final answer is: $\boxed{\frac{W}{3}}$

However, without specific values of external forces and distances, a numerical solution is not feasible here.
