Simple Machines


What is a Simple Machine?

A simple machine is a mechanical device that changes the direction or magnitude of a force.  In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called leverage) to multiply force. 

The 7 simple machines are:
Gears
Inclined Plane
Lever
Pulley
Screw
Wedge
Wheel and Axle

When I Grow Up

When I Grow Up
by Jack Prelutsky

When I grow up, I think that I
may pilot rockets through the sky,
grow orchards full of apple trees,
or find a way to cure disease.
Perhaps I'll run for president,
design a robot, or invent
unique computerized machines
or miniature submarines.


When I grow up, I'd like to be
the captain of a ship at sea,
an architect, a clown or cook,
the writer of a famous book.
I just might be the one to teach
a chimpanzee the art of speech...
but what I'll really be, I'll bet
I've not begun to think of yet.

Bridges Career Research

This is a screenshot from the Bridges career research website.  It is a great resource for researching careers.  You can find out what they do, the average annual salary, education required, and get links for more information.  One of my favorite parts is that you can read an interview with someone who works in that career.  These interviews can tell you the pros and cons of the career.

The Birth of the V-ROD

In class we are watching a video about Harley Davidson's V-Rod motorcycles (pictured above), that shows how the engineers at Harley Davidson used the Design Process to create the V-Rod. 

The VRSC (V-Twin Racing Street Custom) family was introduced in 2001 in a single model called the V-Rod. The V-Rod was developed as Harley-Davidson first "Power Cruiser", designed to compete against Japanese and American muscle bikes. The "V-Rod" made use of the Revolution engine, developed jointly with Porsche that, for the first time in Harley history, incorporates fuel injection, overhead cams, and liquid cooling. The V-Rod is visually distinct from other Harley-Davidson motorcycles. It can be easily identified by the 60-degree V-Twin engine, the radiator and the hydroformed frame members that support the round-topped air cleaner cover. A distinct difference between the V-Rod and all other Harley production motorcycles, is the location of the fuel tank. The fuel tank on the V-Rod is located underneath the seat, placing the driver on top of it, rather than the usual frontal placement, the "tank" in this place is simple dressing, hiding the frame. Loosely based on the VR-1000 superbike, it continues to be a platform around which Harley-Davidson builds drag-racing competition machines. 

Click here to see a video on how Harley Davidson kept their distinct sound in the V-Rod.
Harley Davidson continued to make modifications year after year to the award winning V-Rod.  In 2009, Harley Davidson introduced the V-Rod Muscle, (pictured above) showing that they have continued the 7 step Design Process (listed below) by reviewing their choices.

1. Identify the Problem
2. Collect Relevant Information
3.  Brainstorm Design Options
4.  Evaluate the Design Options
5.  Select the Best Option
6.  Create Model or Implement the Design
7.  Review Choices

What part of the 7 step Design Process do you think is the most important and why?

The Stranger

*** Spoiler Alert***

This is the story, "The Stranger" by Sue Baugh.  Please do not read the ending until you have completed your own ending as part of "The Stranger" assignment. 

After you read it, post a comment about what you thought of the real ending.  Did you like it?  Was it similar to your ending?

The Stranger

Late one Saturday night, a young man was driving home on a deserted stretch of road. He could hear the rain beating against the roof of his car. His headlights cut through a cold mist that clung to the trees on either side of the road. In the flashes of lightning, tree branches seemed like ghostly hands grasping for his car. He could feel the steady drum roll of thunder. What a night to be out! He shivered and wished he were safe at home.

Suddenly, as he rounded a curve, his headlights lit up a young woman standing by the side of the road. Her hair and white dress were soaked from the rain. She looked so alone. He couldn’t just leave her there.

The young man skidded to a stop, then backed up until he could see her face in the window. He leaned over and opened the door.

“Would you like a ride?”

She nodded and he reached out his hand to help her into the car. He shivered at her touch – her hand was so cold!

She smiled at him and said, “Can you take me home? I only live a mile away.”

Now that she was sitting beside him, he could see how beautiful she was. Dark hair framed her face, and her eyes seemed unusually large and sad.

“Sure,” he said. “You must be freezing.” He took off his letter jacket and gave it to her.

“I’m always cold,” she said, and held her hands up to the heater.

He drove ahead, and glanced at her.

“Why were you walking home?” he asked. “Did you have a fight with your boyfriend?”

She didn’t answer. Instead she gazed out the window as they passed a school and a small church. He turned the corner onto a tree-lined street whose cheerful homes seemed warm and safe in the storm.

She sat up. “There’s my house, the two story one on the corner.”

He stopped the car next to the walk leading up to the house. He circled around to the passenger side and helped her out. Her hand still felt like ice. He walked her to the front door, wondering what it would be like to kiss her. They stood on the front porch for a moment, then suddenly she leaned over and kissed him! Before he could say anything, she stepped into the house and closed the door.

He stood staring after her, too astonished to move. Then he turned and walked slowly back to his car. It wasn’t until he was behind the wheel that he remembered his letter jacket. She was still wearing it.

He looked back at the house, but it was dark, and her parents were probably asleep. He didn’t want to wake them up and get her in trouble. Then he smiled. The jacket gave him the perfect excuse to see her again.

The next morning he drove back to the house and rang the bell. An older woman answered the door. She had the same dark hair and sad eyes as the girl.

“Excuse me, can I talk to your daughter?”

“My daughter?” The woman’s eyes filled with tears. “Laura died a year ago last night, in a car accident. It happened about a mile from here.

The young man gasped in disbelief. “But …but I gave her a ride home last night! I walked her to the door, right here. I saw her go inside the house.”

The woman shook her head. “That can’t be. She died a year ago, young man. She’s buried in the church graveyard around the corner. Go see for yourself – she’s in the third row from the front.”

The young man walked down the road to the church. He realized it was the same one they had driven past the night before. The small graveyard was behind the church. He found what he was looking for in the third row.

A white marble headstone was inscribed with the name Laura. The date of death was exactly one year and one day ago. Then he saw something that chilled his blood. There beside the headstone was his letter jacket, neatly folded on the wet grass.

The Exponential Growth of Technology

An Osborne Executive portable computer, from 1982, and an iPhone, released 2007. The Executive weighs 100 times as much, has nearly 500 times the volume, cost 10 times as much, and has a 100th the processing power of the iPhone.
Moore's Law

Moore's law describes a long-term trend in the history of computing hardware.  The number of transistors that can be placed inexpensively on an integrated circuit has doubled approximately every two years. The trend has continued for more than half a century and is not expected to stop until 2015 or later.

The capabilities of many digital electronic devices are strongly linked to Moore's law: processing speed, memory capacity, sensors and even the number and size of pixels in digital cameras.  All of these are improving at exponential rates as well.  This has dramatically increased the usefulness of digital electronics in nearly every segment of the world economy.  Moore's law precisely describes a driving force of technological and social change in the late 20th and early 21st centuries. 

The law is named after Intel co-founder Gordon E. Moore, who described the trend in his 1965 paper.  The paper noted that number of components in integrated circuits had doubled every year from the invention of the integrated circuit in 1958 until 1965 and predicted that the trend would continue "for at least ten years."  His prediction has proved to be uncannily accurate, in part because the law is now used in the semiconductor industry to guide long-term planning and to set targets for research and development.

Ethics in Action: Green Design

 Green Design

Designers are trying to create products that do not harm the environment. They are building automobiles, electronic devices, and schools that use less energy and make less waste. This is called “green design.”


Green Computer from HP

The computer manufacturing company HP has already built a “green” computer. The rp5700 slim desktop PC contains no toxic materials. It is made so that it can be taken apart and recycled easily. For the computer’s casing and packaging, HP used recycled materials.
Going Green – More or Less?

Imagine you are designing a new “green” computer. You could use materials that are good for the environment, but they will cost you more.

You must choose to charge more for the customer or make less profit on each computer you sell.

Write a paragraph explaining what you would do and why.
