WebPhi is the angle that goes from 0 to 2pi in both polar coordinates and spherical coordinates. Set theta=0 (or pi/2) in spherical coordinates, and you directly get the polar coordinates. Why would you switch the angles here? The physics way seems much more consistent to me. WebIf F1 = 30 lb and F2 = 40 lb, determine the angles uand f so that the resultant force is directed along thepositive x axis and has a magnitude of FR = 60 lb.... free mac os software
