QI/ The two structural members, one of which is in tension and the other in compression, exert the indicated forces on joint O. Determine the magnitude of the resultant R of the two forces and the angle which R makes with the positive x-axis. 3 kN „2 kN 30

Two forces are applied to the construction bracket as shown. Determine the angle which makes the resultant of the two forces vertical. Determine the magnitude R of the resultant. F₁ = 800 lb y 70% F₂ = 425 lb x

Compression member AB is used to hold up the 325 x 500-mm rectangular plate. If the compressive force in the member is 320 N for the position shown, determine the magnitude of the projection of this force (as it acts at point A) along diagonal OC. Express your answer in units of N. Report the projection as a positive number. 325 30° O 410 320 180 C B 100
