I made a can crusher or school and it has to use less than 70 newtons (7 kilograms). Mine takes 100 newtons (10 kilograms). How do I make it so it uses less than 70 newtons before tomorrow? please reply ASAP
you have to make changes in converting the power like using more number of teeth in a wheel.
You need to increase the mechanical advantage. I assume this is a hand operated lever type. Make the lever twice as long and you will be under 70 newtons.
