1J30.15 Normal Force of Blocks on Incline

Place three lead bricks on top of a rubber sheet resting on the Force Plate on a flat board to display the total normal force responding to gravity. Then raise the board to an incline to show the decreased readings on the scale, and resolve the forces mathematically.

Three lead bricks sit on a thin rubber sheet which sits on a flat force plate (resembling a bathroom scale). The force plate has been set on a pine board. A level with a protractor indicator sits beside the force plate. The force plate is run by an outdated portable 'computer' that is highly unlikely to work today...

 

 

 

 

 

 

 

 

Three lead bricks sit on a thin rubber sheet. The rubber sheet sits on a flat force plate (an object that resembles a bathroom scale). The force plate sits on a pine board which is inclined at an angle. A level with a protractor indicator allows the audience to read off the angle.
