Hey there! I have an upcoming project to do, just want to gather some ideas, dont mind cause me i'm new to this forum website The budget has to be MYR300.00, USD96.95. Recycle materials are allowed The project is some sort of presentation, where there will be a certain day where we will have our own booth and we have to present our project to all of the students and lecturers The project that we have to do has to be something that will help to overcome world issues such as pollutions or whatsoever For example, a dinamo fixed onto a bicycle, kinetic energy produces electrical energy hence this can conserve energy from power plants OR Solar car, where it will allow us to save the environment by not using alot of petroleum The project has to have full answers in it, for example let's take pascal's principle, hydraulic jack. Questions like :- What is the maximum amount of load can the hydraulic jack lift? What is the amount of force required to lift a certain amount of weight? etc etc Any ideas?
