                  Simple Machines: PPT/Activity

    Greek mathematician, physicist, astronomer, and engineer Archimedes boasted, “Give me a place to stand, and with a lever, I will move the whole world.” Archimedes never moved the world, but he did change the world through the development of simple machine mechanisms.

    In this activity you will explore the function and characteristics of the lever, wheel and axle, and pulley systems. You will see first-hand how simple machines manipulate energy to create a desired output.

    Practice Problems        

    You do not have to look far to see gears. You might not think of an object such as a computer as having a lot of moving parts, but the CD tray on your computer is likely controlled by gears. A traditional watch is full of gears. The watch has one source of power or input that must move multiple hands continuously and at different speeds. Some watches also keep track of the day of the month. This may be low-tech by today’s standards, but imagine the challenge of choosing just the right gears to keep a watch synchronized. In a watch the gears are used to manipulate rotational speed. Gears are also used in many applications to control torque and rotational direction.

    Unit 3:     Electrical Circuits 1.2.3

    Since the late 1800s, engineers have designed systems to use electrical energy due to its ability to be converted, stored, transmitted, and reconverted efficiently into other forms of energy. In the 21st century, electrical energy production, distribution, and application have become consumer driven. Today’s consumer uses electrical energy in all aspects of life, from cell phones and computers to refrigeration and heating and cooling systems, and transportation. Electrical energy, depending on geographic location, is converted from mechanical energy, chemical energy, light energy, and thermal energybefore it reaches the consumer.

    Regardless of the conversion process, electrical energy consists has three properties: currentvoltage, and resistance. Understanding the relationship between current, voltage, and resistance allows engineers to design efficient, safe, and functional electrical circuits. Electrical circuits consist of the following components: an energy source to provide voltage, conductors to allow current travel, insulators to limit current travel, and a load. Electrical circuits provide an uninterrupted path for current travel and are broken into two distinct categories of design: series circuits and parallel circuits.
