More interesting than the simple pulley is the compound pulley.
Now this picture is better than my drawing over here and you can kind of see what's going on.
By using this clever mechanism, we actually let the string pull on the object twice.
This string is pulling upwards as is this string.
If we want to do a force diagram on the subject, we still have (mg) going down
but now the tension goes up twice.
One representing each of these arrows .
What would the tension have to be now in order to balance this 1000 N weight?
