LEGO Brix-Vehicles

Mechanical Engineers build things with moving parts.

A force is a pull or a push. Friction is a force that happens when surfaces rub together. Vehicles must overcome the force of friction. Vehicles also have gears, wheels and axles, these are simple machines. A wheel and axle help move an object. It lowers the friction. The engineers must use the engineering design concept to solve problems. Engineers need to design, build, test, fix any errors and rebuild, retest their design to find the best solution.
