PROBLEM 1. Replace the loading system by an equivalent resultant force and specify where the resultant's line of action intersects the member AB measured from A. 0.5 m -1.5 m- 0.5 m 0.5 m| B 8 kN 6 kN 5 kN 3 m A

The pole OB is subjected to the 6004b force at B. Determine (a) the rectangular components of the force; and (b) the angles between the force vector and the coordinate axes.

The trapdoor is held in the horizontal plane by two wires. Replace the forces in the wires with an equivalent force R that passes through point A, and determine the y-coordinate of point A.

Determine the resultant force or resultant couple for each of the line loads shown. In each case the loading is normal to the line and has constant intensity w0.

Determine the resultant R of the three forces applied to the triangular plate. Specify the coordinates of the point where R crosses the xy-plane

Replace the three forces acting on the bent pipe by a single equivalent force R. Specify the distance d from point O to the point on the x-axis through which the line of action of R passes: 50 lb 40 lb 10 10" 10" 60 lb

Use the rectangular component method to solve the fol- lowing problems. Determine the magnitude R of the re- sultant of the forces and the angle 6, between the line of action of the resultant and the x-axis for F = 400 N 60° 45 F; = 300 N
