1. The problem statement, all variables and given/known data Q) Derive the expression for the equivalent spring constant that relates the applied force F to the resulting displacement x of the system shown in Fig. 1.86. Assume the displacement of the link to be small. 2. Relevant equations I have solved the question but when i checked it on the solution manual, the answer was different. In the solution manual they have approximated the extensions of all the springs as the same but i think they will be different. Please let me know whether my method is correct or the one in the solution manual.

The attempt at a solution There are 2 methods and each leading to different values of Keq. Which method should i follow?
