This past week our class had been building mechanical contraptions using metal aluminium bars, connectors, axles, gears, ropes and wheels. Today we built a dump truck with a working tailgate (large container at the back of a dump truck which contains waste.) The tailgate functions with a lever we built using one medium sized metal aluminium bar attached to an axle which turns 360 degrees. The bar pushes the tailgate upwards causing it to tip things inside of the tailgate towards the ground at an approximately 45 degree angle.
Afterwards we built a functional gearbox which can lift heavy things using a large metal aluminium bar, axles, gears and a rope. We had fun doing this. Thank you EPRO8 for sponsoring us! <3
