A2-2 NAME: Embed your responses in this document. Show work, with proper units. Three forces act on the bracket at point A: FA=100lb, FB-30lb, and Fc=50lb, Fc A FB B FA 70 PO Q: Angle of force FA is given. Using the squares and the given geometry, determine the angles that FB and Fc make with the horizontal. Q: Specify the positive x and y coordinates with the origin centered at point A. Express each vector in unit-vector notation Q: Express the resultant vector R=FA+FB+FC in unit-vector notation Q: Find the magnitude and direction of R with respect to the positive x-axis Q: Sketch the resultant vector in the cartesian coordinate frame.
