A spring-loaded pantograph provides electrical contact through a shoe designed to support a load W when the angle between the equal arms is θ, Fig. 1.25. Each spring has stiffness k and is free of load when oA=a. Find the necessary value of k if the weights of all the parts are neg...
The force–displacement diagram for Node B is presented in Fig. 7. Accordingly, by increasing the number of elements, the linear spring behavior converges toward the theoretical prediction. The curves for 20 and 25 elements coincide, and so the simulated behavior is shown to...
