Question
There are no sections that will allow a single step to solve for the force in CF without knowing the support reactions. Begin by solving for the reaction force at D. Let a positive force act up. Find Dy and the following X, Mo, FCF

Transcribed Image Text:The truss shown in (Figure 1) with L = 1 m is subject to the for
P = 5 kN and P, = 7 kN. Use the method of sections to
determine the force in member CF.
