Cockroach Tractor Pull 1. How many washers will a roach be able to pull? ______________________ 2. Weight of washer _________________g 3. Weight of roach ___________________g 4. Maximum number of washers pulled ______________ 5. Pulling power of roach = Number of washers pulled x weight of washers _______________ g 6. Pulling power if humans had the strength equivalent to roach = Pulling power of roach + weight of roach = x (pulling power of human) _______________________________________________________________ Weight of roach = Weight of human x = Pulling power of human _____________________________________ lbs
