Question

Problem 1. The force P is applied to the cable at the frictionless pulley C to hold the 1200N weight in the equilibrium position shown in the figure. Determine: (a) the magnitude of the force P, (b) tension in cable AB, and (c) tension in cable BC, Please draw the free body diagram of the particle under consideration clearly. B 28 200N Problem 2. A force F of magnitude F-147 Ih is applied to the rod ABC shown in the figure The point B lies midway between points A and C (coordinates of point B are the average of coordinates of points A and C, respectively). The line of action of the force F passes through points B and D. Determine (a) The component of force F along the rod ABC. (b) The component of force F perpendicular to rod ABD. This component is designated as FN. (c) Show that Fr and FN are perpendicular to each other (d) The perpendicular distance, d, between point A and line of action of force F component is designated as Fr

for problem 2, part b, perpendocular to rod ABC not ABD!
