"How much wood could a woodchuck chuck if a wood chuck could chuck wood?" An age old tongue twister that has never been answered. In this rhyme, the common assumption is that the woodchuck is a small furry groundhog like creature, but there is another kind of wood chuck that is not as common but could chuck wood. Here we will explore this path of answering this age old riddle.

In the production of many wood products a common manufacturing tool known as a lathe is used, and to hold the wood in the lathe a chuck is used. In order to calculate the amount of wood a wood chuck can chuck we must first define how the wood will be chucked. When wood chucking the chuck will be spinning around the spindle and an attachment will be used that will act as a catcher that will be on the outer radius of the chuck. We will also be able to calculate the velocity of the wood leaving the chuck and the kinetic energy.


Lathes & Chucks

A LATHE is "a machine tool designed primarily to do turning, facing, and boring. Their versatility permits multiple operations to be done with a single setup of the workpiece. Consequently, the lathe is the most common machine tool." The lathe used to theoretically calculate the amount of wood that can be chucked is the TECHNO CNC WOOD LATHE. This lathe has a spindle speed rate from 500 to 2000 RPM, which will be used to calculate the amount of wood chucked.

The Chuck is an attachment that is the most commonly used way to hold a workpiece on the lathe. It attaches to the spindle on the lathe and is spun by it at speeds up to 4000 RPM depending on the lathe. The chuck that will be used for our calculations will have an approximate mass of 4 kilograms and a diameter of 6 inches.


Wood Chucking

To calculate the amount of wood that is chucked, and the other properties of wood chucking, using the TECHNO CNC WOOD LATHE the following values and assumptions will be used:

* The spindle speed of the lathe has a range of 500-2000 RPM
* The diameter of the chuck is 6 in. approximately 15 cm.
* A one kilogram block of wood made out of American Spruce with a density of .

Perfection in Ursula LeGuin's The Lathe of Heaven Essay

- Perfection in Ursula LeGuin's The Lathe of Heaven Is there such a place where ideal perfection exists. Can our views on social, political, and moral issues ever concur with one another. The answer to these questions is simple - no. The world we live in today is full of social, political, and moral imperfections that hinder our ability to live a life free of evil. In Ursula LeGuin's The Lathe of Heaven, this imperfect lifestyle is the foundation on which the desire for a utopian society sits. The American Heritage Dictionary defines reality as the totality of all things possessing actuality, existence, or essence ....   [tags: Ursula LeGuin Lathe Heaven Essays]

The Physics of the Arc Essay

- ABSTRACT Several researchers have devoted efforts on studying physics of arc and descriptive models are used to explain many arc welding related phenomena. However, due to the subject complexity, doubts still emerge about the mechanisms of some phenomena related to the arc. For instance, the description about electromagnetic interactions with the arc, which governs the arc trajectory and lead to plasma jet and arc blow formation, seems to be yet controversial. Thus, the present study aimed a better understanding of these phenomena....   [tags: Physics ]

- George Orr's Torture by His Dreams in The Lathe of Heaven George Orr is tortured by his dreams because sometimes they come true. The world he wakes up to has changed into the world that he dreamed, sometimes radically, sometimes violently. As a teenager he dreams the death of his aunt and he awakens to finds that she was killed in a car accident six weeks before. He is horrified, and attempts to control his dreaming, but over the years some of his dreams and nightmares come true. Finally by the time he is thirty ( in the year 2002) he is becoming psychotic and he contemplates suicide but then turns to pep pills to stay awake to prevent dreaming....   [tags: The Lathe of Heaven Ursula K.

Essay on The Physics of Roller Coaster

- i: Introduction You apprehensively walk up the iron steps and onto the platform. You’re reluctant to go any further, but your friend eggs you on, saying, “It’s not that fast.” You step into the seat and pull the harness down over you. No, this isn’t the latest, greatest technological frontier. It’s a roller coaster. Since 1804 when the first wheeled roller coaster- called “Les Montagnes Russes”- was constructed in Paris, France, roller coasters have been a staple of adventure and fantasy among children and children-at-heart....   [tags: Physics]

Essay about The Physics of Roller Coasters

- A roller coaster is a thrill ride found in amusement and theme parks. Their history dates back to the 16th century. It all started in Russia, with long, steep wooden slides covered in ice. The idea then traveled to France. Since the warmer climate melted the ice, waxed slides were created instead, eventually adding wheels to the system. The first roller coaster in which the train was attached to the track was in France in 1817, the Russess a Belleville. The first attempt at a loop-the loop was also made in France in the 1850s....   [tags: Physics]

Applications of Physics For Different Industries Essay example

- INTRODUCTION Physics attempts to describe the fundamental nature of the universe and how it works, always striving for the simplest explanations common to the most diverse behaviour. For example, physics explains why rainbows have colours, what keeps a satellite in orbit, and what atoms and nuclei are made of. The goal of physics is to explain as many things as possible using as few laws as possible, revealing nature's underlying simplicity and beauty. Physics has been applied in many industrial fields, which include the air industry, construction industry, automobile industry, manufacturing industry and many others....   [tags: Physics]

The Physics of Car Collisions Essay

- Basic Concepts Issac Newton was the first to state the concepts that are necessary to understanding the physics of collisions. His three laws are used again and again in all the fields of physics: Newton's 1st Law In the absence of external forces, an object at rest remains at rest and an object in motion remains in motion with a constant velocity. This law can be best observed in space, far from the gravity of a star or planet, where there is no friction or air resistance. If, in the middle of deep space, you give a rock a little push, it will continue with the direction and velocity you gave it forever....   [tags: Physics]

541 grams per cubic centimeter has approximate dimensions of 12x12x12 cm.
* An attachment is used to feed wood blocks at a rate equal to the rate of the chuck spinning (1 Block Per Revolution).
* The lathe is run for 1 minute.

At 500 revolutions per minute:

*
500 RPM x 1 Block Per Revolution x 1 minute = 500 Blocks
* 500 RPM / 60 seconds = 8.33 Revolutions per second = 8.33 Blocks per second

At 2000 revolutions per minute:

*
2000 RPM x 1 Block Per Revolution x 1 minute = 2000 Blocks
* 2000 RPM / 60 seconds = 33.3 Revolutions per second = 33.3 Blocks per second


Other Properties

In addition to the amount of wood calculated to be chucked, we can predict the velocity of the wood leaving the chuck and the kinetic energy of the wood.

Velocity:

@ 500 RPM the angular velocity at the Block Center of Mass is calculated by:
1 rev = 2(3.14)(13.625) = 85.6 cm
.856 m / 1 min * 1 min / 60 sec = .01427 m/s
500 * .01427 m/s = 7.135 m/s

the linear velocity at the Block Center of Mass is calculated by:
v = rw
v = (.13625)(7.135)
v = .79365 m/s

@2000 RPM the velocity at the Block Center of Mass is calculated by:
1 rev = 2(3.14)(13.625) = 85.6 cm
.856 m / 1 min * 1 min / 60 sec = .01427 m/s
2000 * .01427 m/s = 28.54 m/s

the linear velocity at the Block Center of Mass is calculated by:
v = rw
v = (.13625)(28.54)
v = 3.1746 m/s

Kinetic Energy:

Angular @ 500 RPM: KE = 1/2 Iw^2
I = SUM(mass * (radius)^2)
I = (4.0)(.075)^2 + (1.0)(13.625)^2
I = .041064
KE = ½(.041064)(5.825)^2
KE = 0.696665

Angular @ 2000 RPM: KE = 1/2 Iw^2
I = SUM(mass * (radius)^2)
I = (4.0)(.075)^2 + (1.0)(13.625)^2
I = .041064
KE = ½(.041064)( 23.3)^2
KE = 11.14663

Linear @ 500 RPM: KE = 1/2v^2
KE = ½( 0.793656)^2

Linear @ 2000 RPM: KE = 1/2v^2
KE = ½( 3.174625)^2
