For 10 points, name these devices which include the pulley, wedge, and inclined plane.
Calculations related to one of these systems are dependent on a distance quantity called the pitch, and in one of these systems, the torque produced by an external force affects a component concentrated closer to the center of mass. For two of these systems, the ratio of outer radius to inner radius and the ratio of sloped length over width give the ideal form of a quantity defined as the output force divided by the input force called mechanical advantage.
