Homework Statement
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.
Homework 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.
