Investigating the Efficiency of Different Pulley Setups Aim In this experiment I will be investigating the efficiency of five different pulley setups. These are shown below. Background on pulleys A pulley one of the simplest mechanical powers or machines consisting of a grooved wheel/roller(s) for a cord or string to pass over a mounted block this is used for lifting a mass or changing direction of power. A pulley is a force multiplier, when x number of pulley(s) are setup with x number of
community. That is why it so interesting in my opinion. One day I was brain storming and this method just popped into my head. My hypothesis states that a bigger pulley on the router of an electric motor and a smaller pulley on the router of an alternator connected to a battery would put out higher amounts of energy than the same or even smaller pulley on the alternator. The interesting thing about this experiment is that the results actually matched my hypothesis. As far as getting this to run in a continuous
Problem: How do pulleys affect the load on a system?" What I’m Trying to Prove: The purpose of the experiment is to find out if the number of pulleys affect the force needed to lift a load. Hypothesis : Yes, we can using simple machines such as pulleys because they increase Mechanical Advantage (MA) by decreasing force of weight used. The more pulleys, the higher MA, hence, lighter load. That is why I think you can lighten a load with pulleys. Materials: 7 pulleys 3 weights Rope Spring(Stretch not
Friction Friction- types of and their effects on forces Definition: Friction- “the resistance that one surface or object encounters when moving over another” There are four different types of friction these are: static, sliding, rolling and fluid friction. The types of friction that occurs between solid surfaces is are static, rolling and sliding. Fluid friction on the other hand only occurs in liquids and gases Static friction: When moving an object resting on a surface it requires more force to
(doorstopper), and to hold together (nail). In this Rube Goldberg machine, however, the wedge is holding apart the two books underneath the lever. It is also the fulcrum of the lever and allows for the lever to be moved downwards at a slanted angle as the pulley system pulls the input side upwards. If it were not for the wedge, the lever would not form an inclined plane at the correct angle. The purpose of a wedge is to convert the force applied to its blunt end into forces that are perpendicular (normal
Simple machines are used to let people do certain tasks without using a lot of force. They increase the effect of a certain input distance, speed, or force. They also are able to help change direction. Simple machines consist of levers, pulleys, inclined planes, wedges, screws, wheel and axles, and gears. 1Some of these simple machines combined create compound machines. Some examples of compound machines are a wheel barrow that consists of a wheel and axle and a lever, and a cork screw which has
An inclined plane can be anything from a ramp, to a jagged road down a hill. Usually inclined planes are used to help lift things, but they’re also used to help an object, such as a wheelchair move to a higher or lower level with less trouble. They help make mobility easier for disabled people, and for transporting items. Inclined planes are shorter on one side, and gradually gain height at the end, the higher the distance, usually the longer the ramp. The inclined plane is the best simple machine
Purpose The machine is a Rube Goldberg machine that turns on a light. It has no practical purpose, and exists solely as art. It is exciting and beautiful to watch, but a machine that takes three times as long to do a task that requires very little effort without a machine has no inherent value. It is simply there as art, as something for people to look at and to enjoy. A Rube Goldberg machine is witty. People like seeing how parts just fit together, how a chain reaction of small parts can do something
kg•m2 0.000503 kg•m2 Analysis: After completing the experiment, the data was transferred from DataStudio to Excel file, Lab9. Next, the points in the data when it started to increase were removed from the data points because that was when the 3-step pulley spun the opposite way of its original direction. This caused the mass hangar to be pulled back up and our experiment focuses on the just the drop. After deleting the excessive data, a scatter plot was created for all five trials for both the No Ring

This mass will be measured in grams. I will put on masses from 100g to 800g. I am going to measure the acceleration of the trolley in m/s as the mass on the pulley changes. As the masses will be acted on by gravity they will extent a force on the trolley and I will use g= 10N/K to work out the force for each mass. Prediction:
rear of the trolley via a pulley system will act as the brakes. Throughout the experiment energy will be transferred into many forms but no energy will be lost or gained. As the trolley is raised it gains potential energy, when released down the ramp this energy is converted to kinetic energy. When the trolley hits the horizontal surface all the energy will be kinetic. As the trolley continues to roll the kinetic energy within it, raises the weights on the pulley system. The kinetic energy
machine can do the work of one extraordinary man” –Elbert Hubbard1. Machines often are used to make life easier for human beings. A simple machine is described as a device used when a fore is being applied to an object. Simple machines include: levers, pulleys, wheel and axle, gears, inclined plane, wedge, and screws. Complex machines are systems of simple machines used together to get work done. Mechanical advantage is how much input work is applied to machine compared to the output force put out by the
negative skew in the results. Mass of the trolley – 98.98g The same trolley will be used. Newton’s second law of motion states that more force is required to accelerate a greater mass. Friction of the pulley The same pulley will be used. Friction between the string and the pulley, or within the pulley, will decrease the acceleration as it will act against the movement of the two masses.
1.6.3. Conveyer Belt: Conveyer belt is a carrying medium to carry the objects forward. A belt conveyor system consists pulleys with an endless loop of carrying medium that rotates about them. One or both of the pulleys are powered with battery to move the belt further. The pulley which is powered is called the drive pulley while the unpowered pulley is called as idler pulley. We are using conveyer belt to carry the material further. When the solenoid valve or motor will be stopped, the conveyer
are wheel and axle, 2 pulleys, multiple inclined plane, and a screw. The device progress’ through the following step: 1. A marble triggers a mousetrap, releasing a peg stuck on a peg board. 2. The peg detaches from the pegboard, releasing a marble. 3. The marble progresses down a marble run going through a wheel and axle. 4. The marble then drops down a small tube, encountering a screw in which it circles around. 5. The marble drops down another small tube, landing in a pulley in which the other end
The purpose of this experiment is to analyze the nature of the resistance of motion by static and kinetic friction. First, the maximum static friction force is attained through a system comprised of a mass hanging from a string nestled on a pulley and attached to a block and force sensor. Secondly, a block is moved at constant velocity to determine what force in the positive direction will match the force of kinetic friction in the opposite direction. Thirdly, data is collected from an accelerating
Physics Principles Behind Sailboats How does a sailboat sail? One might be able to explain how a sailboat sails down wind, because almost everyone has seen some debris, such as a plastic bag drifting through the wind. The cause of this is the force of the wind pushing the bag and this force of the wind is greater than the force of resistance so the result is the movement of the bag. But, how does a sailboat sail against the wind and how does a sailboat sail faster than the wind? Aerodynamics
Define and explain the 6 standard simple machines (Wheel/Axle, Screw, Inclined Plane, Lever, Pulley (or Block and Tackle), and Wedge) Throughout history people have made devices to make work easier. The six simple machines are the most notable advances. These simple machines are the wheel and axle, the lever, the inclined plane, the pulley, the screw, and the wedge. These machines make work easier and more efficient. The wheel and axle is the first simple machine I will talk about. The axle is
Lawnmower racing is a sport that is gaining popularity among men, women, and even children. This addicting motor sport delivers the same adrenaline pumping excitement, as the usual car or motorcycle race does, but is less dangerous. A racing mower is also far less expensive than race cars or motocross bikes. It all started in Wisborough Green, West Sussex, England in 1973, when folks from the town started looking for less expensive alternatives to their traditional motor. They wanted a motor sport
patients do not have any questions and directions given are followed to reduce hospital readmission. They even go with the patient on their first visit to the PCP to make sure all information needed is given to the PCP to ensure better recovery (Nelson & Pulley,
