Friction/Frictionless Devices

  • ME10.2 Inclined Plane     InclinedPlaneFriction

    This is a rotating board with a protractor attached. Place the block of wood on a point and notice when the block will begin to slide down. At that point, the component of gravity parallel to the plane will be slightly greater than the frictional force. The coefficient of friction for wood is 0.25-0.5.

  • ME10.3 Plexiglass Air Table

    This is an air table for the vu graph. When the air from the lecture table is supplied, the class can see the abundance of demos that a frictionless table provides on the vu graph.
