Part B: Combining a Fixed and a Moveable Pulley 1. Set up the pulleys as shown in Fig. 2 (see below). Use the pulley you made from the last set-up. Using a second piece of string, tie the weight to the bottom loop of another pulley (not the fixed one). This will be your moveable pulley. Tie a third piece of string to the bottom loop of the fixed pulley. Thread this string through your moveable pulley. Thread it through your fixed pulley. Attach the spring scale to this piece of rope. 2. Pull the spring scale directly downward. 3. In your data record the force required to lift the weight at and “Fixed Movable”. Investigating Pulleys Question: How do pulleys make our lives easier? Background Information: A fixed pulley is attached and hangs from a solid object. A moveable pulley is able to move.
