ResQuestion: A civil engineer in San Francisco is analyzing stress distribution in a bridge support during seismic events. The force vector acting on a critical joint is given by $\mathbf{F} = \langle 4, -3, 5 \rangle$ kN, and the displacement vector of the joint during deformation is $\mathbf{d} = \langle 2, 1, -1 \rangle$ meters. Compute the work done on the joint, defined as $W = \mathbf{F} \cdot \mathbf{d}$.
