Today buildings, structures and machines are almost always designed by computer-generated diagrams of internal forces. One of the skills required by an engineer is to verify the results of an analysis and to spot internal force diagrams that can not be right. This is why the „Schnittkraftmeister“ was conceived: Students get an idea of internal force diagrams by playful learning. Given is a structure under a static external load. Three different solutions for the diagram of internal forces are shown, but only one is correct. The faster the correct answer is chosen the more points are given. Be careful, when choosing a wrong solution, the game is over and all points for the current level are lost! This serious game is for persons, who have a basic knowledge in structural analysis and of external and internal forces in structures. The target audience are aspiring civil or mechanical engineers.
