If you click on the mouse button, a spring balance appears 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 then the spring scale limit (10 N) are automatically changed. Foreign language versions available. http://www.merlot.org/merlot/viewMaterial.htm?id=74718 This java applet shows the advantage of a pulley. http://www.merlot.org/merlot/viewMaterial.htm?id=74650 In this simulation two masses are connected by a rope running over a pulley. Students can adjust the masses, M1 and M2 , and the co-efficient of friction between M1 and the surface. http://www.merlot.org/merlot/viewMaterial.htm?id=89851 Enter values for the masses of the two balls in fields "Mass1" and "Mass 2״. Then hit go to see them fall. The acceleration of mass 1 isdisplayed. If the friction button is selected, then the mass of the pulley, which may be entered in the field "Mass 3" affects the system. Ifthere is no friction, then the string connecting the masses slides freely over the pulley without accelerating it.
