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.
f my book, or with my class notes. I cannot seem to fully crompehend. I need to pass my next exam of composite functions, one to one functions inverse functions, exponential functions, logarithmic functions, properties of logarithmics, and logarithmic and exponential equations. Everything is based off the book. I have a problem concentrating and im willing to fond a price range if anyone is willing to help thank you
