Given F=8.80 i −10.5 j +22.8 kN, find the component of F that acts perpendicular to member DA such that the vector addition of the perpendicular and parallel components of F (F=F⊥+F∥) with respect to DA equals F. Express your answer in component form. Express your answers, separated by commas, to three significant figures. A three-legged structure is shown below. It is attached to the ground at points B (3.33, 0, 0) and C (-3.33, 0, 0) and connected to...
