work easier. I have several problems: a) I dont have any ideas on machines. B) I need help really in general. So far i have 7 examples them being a wheelbarrow, a pulley, a ramp, an ax(e) and a hockey stick. I was wondering if you could help me explain how they make work easier. Also, I'm having trouble identifying the input and ouput forces on these machines. Please help. Btw, im grade 8.
