Sample Problem 2/4 Forces F₁ and F₂ act on the bracket as shown. Determine the projection F, of their resultant R onto the b-axis. Solution. The parallelogram addition of F, and F, is shown in the figure. Using the law of cosines gives us R² = (80)² + (100)² - 2(80)(100) cos 130° R = 163.4 N The figure also shows the orthogonal projection F, of R onto the b-axis. Its length is F₁ = 80 + 100 cos 50º = 144.3 N Note that the components of a vector are in general not equal to the projec- tions of the vector onto the same axes. If the a-axis had been perpendicular to the b-axis, then the projections and components of R would have been equal. 32 Chapter 2 Force Systems PROBLEMS Introductory Problems 2/1 The force F has a magnitude of 800 N.
