The objective of this lab was to study the change in force using pulley systems. Hypothesis: I think with the weight and the different number of pulley systems being added each time the weight will be easier to lift every time we add a weight. Procedure: To do this lab you must first search different pulley system diagrams. Then you must find a way to make those pulley systems you have chosen work using four items. Pulleys, ring pole, a weight of your choice, Newton spring scale, and string.
The point of using a pulley system is to try and get the weight off the surface. So you must put the strings around each wheel and pull until the weight is off the surface. Once the weight is off the surface you write down using the Newton scale what the force was. You continue this for each pulley done. Apparatus: Pulleys, Newton spring scale, Ring pole, MGM weight Materials: string and scissors Data: Conclusion: Elevators use pulleys in order to function.
A cargo lift that allows items to be hoisted to higher floors is a pulley system.
Wells use the pulley system to bring the bucket up and down the well out. Construction pulleys are used in order to lift and place heavy materials. Curtains at a theatre are moved using pulley systems. Blinds on windows operate using a pulley system to move the blinds up and down. Flagpoles use pulleys in order to lift the flag up or to bring it down.
Pulleys can be used to place bird feeders high in trees or on poles A crane is a type of pulley that is used in construction. Sails on sailboats are raised and lowered using pulleys.
Garage doors raise and lower use a pulley system. Rock climbers use pulleys to help them to climb. Escalators use pulley systems to function. The examples above, a cable system works in order to make lifting easier or to make moving items easier. Pulleys are important to being able to move and lift very heavy or large items. The pulley system uses Newton’s third law of motion. Newton’s Third law is a force is a push or a pull upon an object that results from its interaction with another object.
