Three forces are applied to the beam. F₂ = (-250 i + 6503 + -300 ) N. Variable F₁ F3 d₁ d₂ d3 Value Z 300 N 350 N 2 m 2.5 m 0.5 m F2 d3. d2 d1 F₁ Values for the figure are given in the following table. Note the figure may not be to scale. F3 Y → a. Replace the force system with an equivalent force, FR, express as a cartesian vector. b. Replace the force system with an equivalent couple → moment acting at point 0, (MR)o, express as a cartesian vector. Round your final answers to 3 significant digits/figures.

The bar OABC has multiple bends in different directions. It has a force F₁ = {-100 - } N applied at point B, and a force F₂ = {-100 + 300 - 3+100 · } N applied at point . C.
