To prepare for the upcoming industrial engineering challenge, students have been creating and experimenting with pulleys, and wheel and axles. First, students were asked to create a prototype that included a working wheel and axle. The criteria used to determine if it was successful was when placed on an inclined plane, the wheel and axle must roll down the plane. The students used their creativity and were very successful creating tricycles, cars, bicycles, and other types of vehicles. Next, the students experimented with pulleys. They were given a pulley, a water bottle, and a spring scale to measure the amount of force that is needed to lift the water bottle. Soon, they will compare the amount of force necessary to lift it with a single pulley, to a double pulley. What pulley will require less force? The students can't wait to check their hypotheses! |
