30 Chapter 2 Force Systems Sample Problem 2/2 Combine the two forces P and T, which act on the fixed structure at B, into a single equivalent force R. P = 800 N T = 600 N Graphical solution. The parallelogram for the vector addition of forces T and 1 Pis constructed as shown in Fig. a. The scale used here is 1 cm 800 N; a scale of 1 cm = 200 N would be more suitable for regular-size paper and would give greater accuracy. Note that the angle a must be determined prior to construction 6 m A a C/60° DI of the narallelogram From t+he given fimure 3 m
