HW1.4. 2D Moment resultant Two forces lying in the x-y plane are defined by their magnitudes and direction angles, as shown in the figure below. Force F₁ has a magnitude F₁ = 360 N, an angle 0₁ = 109°, and acts at point A (310, 0) mm. Force F₂ has a magnitude F₂ = 270 N, an angle 02 = 56°, and acts at point B = (0,385) mm. Determine the total moment about point O due to these two forces. Remember to follow the standard sign convention for clockwise (-) and counter-clockwise (+) moments. y B 10 02 F₂ F₁ A 0₁ X TEGINGEN
