Fig. 341. Problem 293. Draw an equilateral triangle ABC with 1Q = 5 Ihs., and S = 3 lbs., heparallel forces acting at thepoints A, B, and C. Determine <the resultant force. Unit -§- =1 lb. Fig. 342. First determine the resultant ofthe forces S and Q. As S + Q — 8,divide CB into eight equal… … Fig. 342. GRAPHIC STATICS 557 sions from B draw the resultant r parallel to the other forcesand equal in length to S + Q (8). Draw a line FG- perpendicular to r, and meeting the-force Pproduced.
