The topic of today is the Ramp. Ramps have been used since ancient times to help move heavy objects or large quantities of materials from one level to another. Today, automobile transport services use the ramp on their trucks to load multiple vehicles on one transport. In the class, the students built the model ramp and the box frame in order to investigate how angle and wheels affect the needed effort.
Two students built one model as a group, then they conducted experiments by using effort weight to pull their box frame from the bottom of the ramp to the top. They tested their built models on three ramps with different angles, then compared the mechanical efficiency of different ramp systems. The STEM information behind this section is the ramp’s mechanical advantage. All students finished the model and experiments, they enjoyed the class.
