Pulley

As shown above we have a weight hanging below a pulley and force sensor, which converts the downward force acting on the rope to a horizontal force acting on the cart. Below the car we have our track to keep the cart guided straight and below that we have our table and shims when necessary. Once we were…

discovered the law of the lever, which states that if the distance between the fulcrum and the input force is greater than the distance between the fulcrum and the output force, then the lever strengthens the input force. Finally, he invented the first pulley, which is another simple machine that is used in everyday life. Archimedes, aside from making findings in mathematics, made plenty of scientific discoveries as…

still had eight steps. Another change I made was instead of having a toy car roll down a ramp at the beginning, I changed it to a toy train down a bumpy hill of train tracks. I also used many Legos. I used it for my levers and my pulley instead of using a real pulley and wood levers. The one last big change was that I took away the screw and replaced it with a ramp. Those are the changes in my prototype phase. I encountered a lot of problems. One of which is measuring the Tetherball to hit…

Rube Goldberg was a very famous,prize winner cartoonist.He was born July 4,1883 in San Francisco.He was a man with a big imagination and enjoyed to entertain children.Rube was very creative with his cartoons.He worked hard to achieve his most important achievements.Mr.Goldberg believed that he would help keep inventions alive throughout his legacy.He attended U. Cal Berkeley and received a degree in engineering.His first job was at San Francisco Chronicle and it led to a lot of success.One award…

Specify the sources (causes) of friction. The causes of friction in this lab come from three different sources. One is the string sliding over the pulley wheel. Another is the pulley wheel turning on its axle. Also, the string sliding through the hole; all these cause friction in our experiment. Glider on Frictionless Air Track Lab The acceleration of the glider can be calculated by tracking the speed as it passes through the two photogates. On the frictionless air track a glider is placed on…

levelled, this step is really important in order to get accurate results(Pic2). Then, connect the photogate to the LabQuest and start logger pro on the PC. Open the Probes and Sensors folder, then open the photogate folder, finally open the file (Pulley). We attached the fishing…

What is Red Cord? Red Cord was designed and developed in Norway by a carpenter/gymnast named Kare Mosberg . Sailing was another one of his passions and it shows in the way his equipment operates. He created this system as a means of alleviating back pain. The idea is to improve muscle alignment and functional strength from the inside out by working the body more efficiently. Red Cord will awaken dormant muscles and release constraint in a short period of time. This tool will help you gain more…

Also another name for a pulley system is called a block and tackle. Door Knob: A door knob is considered a wheel and axle because it contains a wheel that is attached to an axle that allows for the wheel to move and helps magnify the force you exert. Ramp: A ramp is considered…

The legs of Shere Khan will have one active joint on each shoulder and hip and then one passive joint on each leg. A pulley system will be used in each leg in order to keep the joints of the leg synchronized in motion. Alongside the pulley system will be a suspension system that connects the top half of the leg to the bottom half. The suspension system serves the purpose of ensuring that each leg will move in a fluid motion as…

way to lift heavy objects without all the ropes, claws and wheels? Well not anymore, ever since the hydraulic crane which uses the force of water and pushes or pulls throughout the pipes and pulls up heavy items. This has been an innovation in the pulley and regular cranes. With something good there is one bad, if a person were to use pipes or steel which one would be more sustainable and last longer? As in all the other cranes this specific one could be made with either of the two. Finally,…
