ME4.10 Cart on Inclined Plane
A car is placed on an inclined board. A string is attached to the end of the car and is strung up the incline, over a pulley at the top and then straight down. A mass is attached to the end. Another string is attached to the top of the car and is strung so that it is exactly perpendicular to the car over a pulley. Again a mass is attached at that end. After a bit of Newton's second law and trigonometry, the masses are 330gm for the parallel string and 570gm for the perpendicular one. The demonstration is that when the inclined plane is removed, the car is suspended in mid-air with the same angle.
