Determine the equivalent resultant force.

Express your answer to three significant figures and include the appropriate units. Assume the positive direction is upward.

In $($Figure $1),w_1=2\mathrm{.}5k\frac{N}{m}$ and $w_2=8k\frac{N}{m}$ Replace the distributed loading by an equivalent resultant force and couple moment acting at point $A.$
