Description:
Shows a summation of forces keeping a cart at equilibrium. The inclined plane is at 30 degrees and the cart has mass 1kg. Masses on pulleys mimic the normal force of the plane and the tension force that would be needed to keep the cart from moving down the plane. Once the masses are set suepended by the pulleys the incline is removed, the cart stays at rest at the angle because the sum of forces is zero. Normal force is mimicked by an 866g mass on a string perpendicular to the plane, static friction is mimicked by a 500g mass hanging from a string parallel to the plane.
