- The forces P1=110lb,P2=200lb, and P3=150lb are equivalent to a single force R. Determine (a) the magnitude of R; and (b) the coordinates of the point where the line of action of R crosses the yz-plane.arrow_forwardThe three forces of magnitude P can be replaced by a single, equivalent force R acting at point A. Determine the distance x and the magnitude and direction of R.arrow_forwardKnowing that the resultant of the two forces is vertical, determine the anglearrow_forward
