Variable Value F 85 lb F2 50 lb a b 2.5 ft 6 ft d 03 9 ft 1 ft Values for the figure are given in the following table. Note the figure may not be to scale. Variable Value 85 lb 50 lb 2.5 ft F F2 b 9 ft d 1 ft 6 ft a. Write each force (F1, F2) as cartesian vectors. > b. Find the resultant force FR, express as a cartesian vector c. Find the magnitude of the resultant force FR d. Determine the coordinate direction angles of the resultant force FR i. ii. B iii. Y Round your final answers to 3 significant digits/figures. TE = F2 = ( FR= FR= = ( II 2 + k) lb 2 + + k) lb + + k) lb lb degrees B = ( degrees Y = ( degrees Ball joints connect the ends of each of the struts as shown. The resulting structure supports a force of F = 2000 N which lies in the xz plane. a.) Determine the angle (in degrees) between strut AD and strut AC. r b.) Determine the dimension g such that the force F is perpendicular to TAC. 2013 Michael Swanbom cc 10 BY NC SA B Z C A al x4*1 h g F k d D y Values for dimensions on the figure are given in the table below.
