Pulley Essays

mousetrap and the string with a nail we used as a pulley. So when the mousetrap would set off it would pull the string in the opposite direction. The nail, string, nail, and balloon were both required to be used in our project. The fourth step,golf ball released. The slide was connected to hot wheels tracks. We had some jenga pieces and duct tape holding the marble slide up. Also, we hammered the slide to the wood with the nail that acted as a pulley. The slide would be classified as a inclined plane

He went over 4 types of relationships between linear and angular kinematics – 1 Displacement (s or d=Θr), 2Linear Velocity resulting from length of radius (v=rω), 3Linear Velocity resulting from angular velocity(v=rω), and 4 Angular velocity resulting from manipulation of length of radius (ω=v/r). Relationship #1 – Displacement S or d=Θr (Θ, the angle measured in degrees or radiants or revolutions and (r) radius measured in meters). In the video

and the human benchmark. The friction always is the main issue of any experiments. In the lab, the friction still affect the experiment a lot. There are two different frictions affect our Atwood’s machine which is the air frictions and frictions of pulleys. In the dictionary, the air friction is the force that in the opposition to the relative motion which is act on the object as it passes though the air. (What is air

The excerpts “I Hated Tonto (Still Do)” by Sherman Alexie and “An Open Letter to Johnny Depp’s Tonto” by Natanya Ann Pulley, critique the cultural depictions of cinematic characters through remarks of personal dissatisfaction and experiences. In both their excerpts, Alexie and Pulley address their dislike with the belittlement of the Native American identity that the character Tonto contributes to. In the excerpt “I Hated Tonto (Still D0)” Alexie states, “When it came to the movies, Indians had learned

second instance is when the weight is added into the pulley system, the harder it falls into the cup going down the higher the other cup lands. The third instance is after the chain of dominoes collapse and send the marble rolling down the inclined plane. The speed of the changes the distance it will go, therefore it had to be the exact acceleration in order for it to land into the cup. Negative Acceleration is shown when again in the pulley system whereby the string and force of the cup the second

inventing many mechanical tools which have affected our history and the modern day world. In one case, Archimedes took the basic pulley and created a bigger compound system with additional non-stationary pulleys which allowed a person to lift great weights with only a fraction of the effort. Historically, he used a crane-like construction which used the compound pulley system to lift large Roman ships out of the sea, and drop them back down, causing them to break

wood frame about knee high, and attach the door to serve serve as the lid. If your door-lid is heavy, use sturdy hinges. For windy areas, attach a screen-door hook and an eye-bolt to secure your lid. Add a Pulley System Get out the tools, a pulley and some rope or steel cable. Attach the pulley to a stationary

Nifty Lifting Machine Report Questions Use complete sentences to answer the questions. Explain what knowledge was gained when creating the prototype of the nifty lifting machine. When creating the prototype, the group noticed a few errors. The first idea of a wheel and axel did not work, and the wheel and axel was not stable and fell apart. What the group had to do with the wheel and axel was to make the wheel and axel stable by making a whole new base, which the group did. The knowledge the

brochure that explains all the design features and their reasoning for choosing them. The main focus for this unit is to provide students with the opportunity to enhance their critical thinking skills about geometry and spacial senses, while integrating pulleys and gears from the science curriculum. The unit will also meet various expectations from the Language and Art curriculum. Subject Area(s): (Tip: Check all that apply) ☐ Health & Physical Ed.

1. What simple machines did you incorporate into you nifty lifting machine? In our nifty lifting me nine we used two simple machines. We used a pulley system which is one simple machine. The pulleys are what made pulling the can up the five centimeters. We also used a wheel and axle which is the crank that we used to pull up he cans. 2. Explain what knowledge was gained creating your machine in your prototype. I gained lots of knowledge during this project because we had a lot of free reign

Sometimes, some parts of the machine did not trigger or work. I had to make changes in order for each part to work. For instance, when I first tested my pulley, it was very unstable. Each time I tested my machine, the pulley was usually the part that messed up the whole thing. I had to make it work by using different materials on each side of the pulley. I switched the plastic containers with paper cups, and it worked very well. Another example is that my lever did not always work when I tested it. I

A pulley station will be required for these exercises. Stand in the middle of the machine, hold your arms by your sides and grab the handles. Then bring your arms together in front of you, then cross them and then return them into the initial position. Going

about simple machines. Rube Goldberg was a man who created cartoons, was an engineer, author, and artist. He created many things and inspire many people. Rubes machine was something that could incorporate the six simple machines lever, wedge, Pulley, wheel and axle, inclined plane, and screw. These all ended up in one way or another using Newton's three laws of motion. All having to do with an object will remain in motion until a force acts on it. An object will accelerate in the

contributed heavily to engineering because engineering heavily consists of geometry and the study of how different shapes and sizes can affect the way something might work. For example, if an engineer were to create a pulley, they would have to first think of a design for that pulley and

Rube Goldberg machines have fascinated the scientific world for years. Rube Goldberg, the person behind all this, was a Pulitzer-prize winning cartoonist with a high passion in engineering. A Rube Goldberg is a complicated machine created to do a simple task, therefore it 's main purpose to be popular among many schools because it teaches engineering in a more fun way. This Rube Goldberg 's task is to fill up marbles in a flower vase through a chain reaction. Energy is transferred through the contraption

elbow. Cords were attached to the forearm and threaded through pulleys, to represent either the biceps or the triceps. Force sensors were attached to the cords or the model's hand, to measure the amount of force applied during the activities. Any recorded data was exported to a computer for analysis. In activity 1, the shoulder was locked at 0°. A cord was attached to the standard biceps insertion point and threaded through the pulleys to simulate the biceps. A force sensor was attached to the free

results." Within Rube Goldberg machines, it was extremely common for Mr. Goldberg to incorporate the six simple machines, due to their helpful nature to complete his wanted task. The six simple machines include: pulley, lever, wheel and axle, inclined plane, screw, and wedge. First, a pulley is a wheel with a lipped ledge along with a rope or string wrapped around the wheel in order to help lift/move

Also, while weighting the hanger and slotted, students have to record the measure and force, on when pulley pulling down the mass at the exact position over the radial. After getting the measure, remove the weight hanger. According to your lab instructor, all students should wear safety glasses because it applies torque to the shaft in the center pole

out is that a domino is a lever. Since the falling of each one on top of each other happens, this happening is a lever. Another thing I learned, was that I could make a pulley grooved rim by putting a water bottle cap in between 2 pieces of circular paper, which is on a wooden stick. Unfortunately, I didn’t use this idea for the Pulley would move sided to side, but I still learned something new for Youtube thought me an idea. The last and most important thing I learned is that you should Never Give
