Components Of The Worm Drive Gearbox

One of the most fun projects this year, building mousetrap racers. With this project, however, challenges arose. Attaching the wheels to the axles, for example, presented a major problem. The dowel used was .75 inch and was too large to fit in the center of the DVD. Using washers and bolts was thought of, but they proved to be too heavy. In the end, bottle caps and screws worked to secure the wheels to the axles. The bottle caps were wide enough that when fitted against the DVD they wouldn't go through the hole. Another challenge was placing the mouse trap as far from the drive axle as possible without impeding the car’s movement. So an arm extension on the mousetrap was not constructed so upon snapping it would not hit the front axle.

In this case we need to overcome the friction force from the axles, and tires to be able to power the vehicle by mousetraps far enough. There is a coefficient of friction between the axle and the bearing where the axle sits in the bearings and does not spin together so that is where most of the friction is created. The front wheels currently are hard rubber, and the rear wheels are currently cutting disks which are a hard material and very skinny, creating a very little amount of friction. The total force of friction would need to be less than the force of the mousetraps on the axle throughout the traps angular travel. Methods that were used to reduce friction consists of using lubrication on the axles to make it easier to spin, use skinnier wheels to reduce friction from the ground, and making the vehicle lighter with a simpler design.

Cumberland Metals Industries developed a new type of cushion pad for pile drivers made of curled metal. The 11.5 inch “Cumber-Coil” was tested by two different companies on two different projects and was found to far exceed the performance of the existing market-dominant product, the asbestos pad. The Cumber-Coil weighed half what the asbestos pad did and boasted a 33% faster driving time, 60% reduction in heat generated, and 400% less time wasted changing pads.

The outer racer of the bearing is fastening into the boss. The whole subassembly is then attached with the steering arm, stub axle by means of welded joints and the plate welded to the chassis by means of Rod end bearing(2). The steering arm is joined with the steering rod by swivel joint as shown in the fig1.

a) When the lever is winded up and all set for release the Mousetrap Car (MTP) has potential energy that will be used to accelerate the car. 2) When the lever is released the string is pulled from its ready position on the axle causing the level to pull the string causing a pulling force on the string by the lever. 3) When the lever is released and the string is pulled the back wheels of the MTC are beginning to move because of the potential energy that is now kinetic energy which causes rolling friction between the Mousetrap Cars wheels and the ground. 4) The MTC is now accelerating at a certain speed from it's point with the string being pulled by the lever until the spring is snapped, which then causes the MTC to

We have an antique hayrack gear shaft. We used this and some boards for our competition.

Crank a novel written by Ellen Hopkins. The events that occur in the story are loosely based off of events that befell the author's daughter, as she tells in her authors not “While this work is fiction, it is loosely based on a very true story- my daughters.” The novel Crank begins with an introduction to the main character Kristina, and Bree her alter ego. Kristina then speaks of her trip to visit her father. While visiting her father she meets a boy named Adam, or “Buddy”, who gets her addicted to drugs and brings out “Bree”. “Bree” is the most self-destructive personality traits of Kristina. Kristina spends the rest of the book either giving into “Bree” or fighting her. In the end, Kristina's’ better side wins when she is impregnated by

For more than five years, NASA’s Curiosity rover has been roaming around the Mars. While it’s been great success, the lonesome robot is now showing the sign of aging, with its broken wheel. Even NASA’s modern technology couldn’t save them from the rigorous weather of Mars. To solve this problem, NASA has gone back to the middle age to create a superelastic tire. Based on the principals of chainmail armor, this game changing tire can repel more deformation compared to any other non-pneumatic tire. Besides, this superelastic tire could survive any kind of extra planetary abuse and ensures better tractions in next-generation rovers.

Making the car and wheels too light caused problems, though, that’s why I paid close attention to the way my car was proportioned and chose four wheels on each axle all the same size. The reason why I chose four wheels all being a large size for each axle is because larger wheels cover more ground than what smaller wheels can do in the same amount of time.But, both sets of wheels will not affect how a car does at rest. When an object at rest (The car) will remain at rest, the more wound up the string on the mousetrap car is the more force that will be produced on the impact of the hatch releasing causing more acceleration, the reaction to the string causes the force to fly forward. But I also didn’t interpret the way I built my car the way everyone else had, originally my car would need the arm to be set to actually accelerate so that when you pushed down/load the arm, the string is would be compressed, causing the vehicle to accelerate forward. But that changed because of the reaction my car would have with the original setup, spinning in random directions because of how light my car was my second test

The central idea of the passage is that worm like creatures live i total darkness and the story is about how they have adapted and how do they stay alive. On the ocean floor there is small vents coming from volcances and the creatures saty on the vent and that is how they stay alive because while beging on those vents there is heat transfered into there enrgey and food. and so that is mainly the whole passage is how they stay

Being a worm the Zombie worm has no body parts and even lacks a mouth and gut. Scientists are puzzled by this because of the worms unique diet, the worms drill into the bones of dead whales and extract rich nutrients.The skin cells of these structures produce acid, which dissolves the bone, allowing the worm to extract the nutrients. These worms depend on internal bacteria to digest the oils and fats to withdraw from the whale-bone diet.The Zombie worm definitely deserves its unusual name for its unbelievable way of life.
