by the thickness of the bigger end. MA= l/w
MA= Slope length/Width Description of the wedge This machine is basically an inclined plane turned on its size. A wedge helps you push things apart easier. The wedge can be round. Basically it works like a ramp: the narrower the wedge the easier to force it in and push things apart.
