You can raise or lower the load with the mouse. If you click on the mouse button, a spring balance will appear showing the tension in the string. You can change the weight of the load and the hanging pulley(s) by using the appropriate boxes. Inputs higher than the spring scale limit (10 N) are automatically changed.
