This java applet shows the advantage of a pulley.
1. There are three sets of pulley.
2. Double click within those block to change its mass.
Left click to decrease one unit.
Mass of those block are shown in blue.
4. Gravity pulls down one the block with force Mg.
If the total force acting on the block is zero, it is in equilibrium.
Otherwise, the block is under acceleration(animation starts).
His weight is 500N and the rope, unknown to him, has a breaking point of 400N.
Why doesn't the rope break when he is supported as shown to the left on the above picture?
One day Harry is painting near a flagpole, and,
