Hey guys! I'm new to Physics Forum and I have a question. I am building a mousetrap car for my 8th grade science class and have run into a problem. I have built a pretty sophisticated pulley system using a cassette tape. The lever arm and string turn the cassette tape which turns the drive axle. I am using two records as my back wheels, and I fear that they are too heavy. Whenever I arm the car and set it down, nothing happens. It does spin very quickly if I give it a little spin.
I will post some pictures of what it looks like.
