About this app
In this simulation, you will find the jib arm of a crane, a hydraulic cylinder, pins, a platform, bags of cement and a crane car. These elements will allow you to assemble a scale model of a crane, which is based on the operating principle of the application of the lever. You will need to analyze the torque exerted by the forces present in the arm of the crane in order to determine the force which must be exerted by the cylinder in order to keep the system in equilibrium.
