How much is 4 bricks?



Wedges are sort of like 2 ramps put together.
In this set up the block can be moved up by wedge.

Feel how much force the small angle takes and how much different the effort feels for the steep angle.


We are pulling up the weight bricks at different angles

They takes more force to pull up when the angle is bigger.

Perhaps the blocks were pulled up along ramps that were not steep.
