Darn! I should have watched this video before I applied for my patent, I could have made my invention even stronger. Oh well I guess I could modify it.

thanks

Omg, thank you, your 240p video helped me understand physics in 10 minutes than real life day in an entire 50. God bless you sir.

plz explain the mechanical advantage of single moveable pulley.plz its urgent....

Hi I got a problem dealing with windmill lifting up a weight that is 6.5 Kg. i have to build a windmill that could lift 6.5 Kg weight up to 0.75 meters up. How would you do it?

@cmcespedes2 The force you need to apply to lift the weight is reduced using the wedge. That is what mechanical advantage really means. Think like this - You carry a 10 kg box from ground (its heavy), you slide it using a lever, you'll need less force to carry the box. Do you get it now? if not, just try and see for yourself.

It is difficult to lift a heavy filing cabinet onto a truck. Take a ramp with a 30 degree slope, tilt the cabinet back toward the truck, to the point of balance and then just gently rock it up the ramp. One man job!

you are the reason im passing physics

hnjnnnnnnnnnnnnn,

work in cant be equal to work out. it may theoretically true but not practically...such machines are ideal or perfect machines which doesn't exist in real sense
