Solve this problem using the technique ot virtual work:

A $600-N$ load is applied to the linkage at $B.$ The spring is relaxed when members $AB$ and $BC($each of length $0\mathrm{.}300$ m $)$ are horizontal, and its spring constant is $2\mathrm{.}5k\frac{N}{m}.$ Determine $$ at equilibrium. Use Desmos or a similar program to solve the equation you end up with, and include a screensnot in your soiunion.. answer: $,40\mathrm{.}2$
