Niclas recently sent me some questions to answer, and here they are.

The first question was : 
1. Tom made a chassis in his robotics class and he has to re-create one side at home but he can only remember that the size of the vertical and the diagonal Lego bits. The diagonal beam was five units and the vertical was three units. How long was the Horizontal beam? I realized that the pythagorean theorem could be (should be) used in this question, as it is a right triangle. So, 3squared + x squared = 5 squared. This is a commonly known "special triangle, 3,4,5. 9 + 16 = 25 Then, we move onto the next question, when was lego technic introduced? Well it was first introduced in 1977 as the expert builder series, then in 1984 it was renamed to the now famous Lego technic. Lego bricks are measured in units called FLUs or Fundamental Lego Units, but can also be measure in the metric system as seen above.
