Simulators for Ages 16-18

For students aged 16 to 18 who are heading toward engineering, the numbers matter. These simulators go beyond showing how a machine moves: they calculate the gear ratio, torque and power of every shaft in a gear train, the force needed in a block and tackle system, the speed ratio and slip of a belt drive, and the efficiency of a 4-stroke engine from its pressure-volume diagram. They are designed to check worked problems: solve one on paper, enter the same data and compare your results with the simulator.
