Rope wrapped around axle attached to box Ramp length = 60 inches 1. What two simple machines make up the complex machine? lever Weight of box = 495 lbs B. inclined plane 2. What is the mechanical advantage of the complex machine? Hint: add the mechanical advantages of the two simple machines. MA-30 MA length Theight 60 la MA-11 JP=5 1=60 3. How much force (weight) must be applied to the handle of the crank to pull the box up the ramp (assume no friction)? 4.
