Playground seesaws usually have Playground seesaws usually have handleshandles for the riders to grip for the riders to grip as they sit facing each other. One problem with the seesaw's as they sit facing each other. One problem with the seesaw's design is that if a heavier child allows herself to hit the ground design is that if a heavier child allows herself to hit the ground suddenly after jumping, or exits the seesaw at the bottom, the suddenly after jumping, or exits the seesaw at the bottom, the lighter child may fall and be injured. For this reason, seesaws lighter child may fall and be injured.

FLYWHEEL ENERGY STORAGEFLYWHEEL ENERGY STORAGE

       

Flywheel Energy Storage (FES) works by accelerating a rotor to a very high speed and maintaining the energy in the system as inertial energy. Commercially available FES systems are used for small uninterruptible power systems. The rotors normally operate at 4000 RPM or less and are made of metal. Advanced flywheels are made of high strength carbon-composite filaments that spin at speeds from 20,000-100,000 RPM in a vacuum enclosure. Magnetic bearings are necessary as speeds increase to reduce the friction present when using conventional mechanical bearings. Quick charging is done in less than 15 minutes. Long lifetimes of most flywheels, plus high energy densities (~ 130 Wh/kg) and large maximum power outputs are positive attributes. The energy efficiency (ratio of energy out per energy in) of flywheels can be as high as 90%. Since FES can store and release power quickly, they have found a niche providing pulsed power

Generators and motors are very closely related and many Generators and motors are very closely related and many motors that contain permanent magnets can also act as motors that contain permanent magnets can also act as generators. If you move a permanent magnet past a coil generators. If you move a permanent magnet past a coil of wire that is part of an electric circuit, you will cause of wire that is part of an electric circuit, you will cause current to flow through that coil and circuit. That's current to flow through that coil and circuit. That's because a changing magnetic field, such as that near a because a changing magnetic field, such as that near a moving magnet, is always accompanied in nature by an moving magnet, is always accompanied in nature by an electric field. While magnetic fields push on magnetic electric field. While magnetic fields push on magnetic poles, electric fields push on electric charges. With a poles, electric fields push on electric charges. With a coil of wire near the moving magnet, the moving coil of wire near the moving magnet, the moving magnet's electric field pushes charges through the coil magnet's electric field pushes charges through the coil and eventually through the entire circuit. and eventually through the entire circuit.

One watt is a very small amount of power. It would require nearly small amount of power. It would require nearly 750 watts to equal one horsepower. A kilowatt 750 watts to equal one horsepower. A kilowatt represents 1,000 watts. A kilowatt-hour (kWh) is represents 1,000 watts. A kilowatt-hour (kWh) is equal to the energy of 1,000 watts working for equal to the energy of 1,000 watts working for one hour. The amount of electricity a power plant one hour. The amount of electricity a power plant generates or a customer uses over a period of generates or a customer uses over a period of time is measured in kilowatthours (kWh). time is measured in kilowatthours (kWh). Kilowatthours are determined by multiplying the Kilowatthours are determined by multiplying the number of kW's required by the number of hours number of kW's required by the number of hours of use. For example, if you use a 40-watt light of use. For example, if you use a 40-watt light bulb 5 hours a day, you have used 200 watts of bulb 5 hours a day, you have used 200 watts of power, or .2 kilowatthours of electrical energypower, or .2 kilowatthours of electrical energy

The transfer between shafts is accomplished by gears, belts, chains or other similar means for accomplished by gears, belts, chains or other similar means for matching the torque/speed characteristics of the interconnected matching the torque/speed characteristics of the interconnected shafts - eg. a car needs gears between the engine crankshaft and shafts - eg. a car needs gears between the engine crankshaft and drive wheel half-shafts.

 Pulleys-Belts to Transmit/Modify Motion

Mechanical components are used to satisfy many engineering design functions. For example, when a mechanism includes a motor/engine for power generation, mechanical components are used to transmit the motion and power of the motor/engine, to other locations, to reduce speed provided by the motor/engines, to transform the motor/engine motion to a different form (e.g., rotary motion to oscillatory or linear motion), to actuate many subassemblies without requiring multiple motors/engines, to change the direction of motion, etc. In the previous section, we studied the application of pulleys (combined with rope/cable) to lift objects. Pulleys, as lifting devices, provide the design function of changing the direction of motion and force. Multiple pulleys also provide mechanical advantage, even though the friction between the pulley and rope/cable will increase as we increase the number of pulleys.In this subsection, we extend the use of pulleys to change the direction of rotary motion (as opposed to linear motion to lift objects), to reduce or increase speed, and to transmit power. To achieve these design functions, a belt component replaces the rope or cable. The following figure illustrates the two basic arrangements of pulleys-belts.
