3 types of modern wagon design materials: Steel ~ Wood ~ Plastic
3 types of wheels that can be found on the Radio Flyer Wagons:
- Pneumatic- this wheel consists of an inflatable air tire (or a "Balloon Tire") surrounding a steel wheel.
- Semi-Pneumatic- this wheel has a rubber tire tread. But unlike the pneumatic wheel, these wheels are not inflatable.
- Molded Wheels- This wheel is a durable plastic wheel. Unlike the pneumatic and semi-pneumatic wheels, the molded wheel does not have a steel wheel or a rubber tire.

3 types of tires being recalled due to possible design problems:
- The 15-inch ATX
- The 15-inch ATX II
- The 15-inch Wilderness AT
(New evidence suggests that the practices of both Bridgestone/Firestone and Ford Motor Company were involved in the widespread failure of the tires.)

3 types of tires were legal in the New York State Ice Racing Association (NYSIRA) and the Adirondack Motorsports Enthusiasts Club (AMEC) in 1997: Studded tires ~ Screwed tires ~ "Specialty, spec" tires.

3 Grades for temperature resistance of a tire (branded on the sidewall):
- Grade A = maximum performance level. It withstand a 30-min run at 115 mph.
- Grade B = the tire performs well at 100 mph, but not at 115 mph.
- Grade C = the tire can not withstand a test for a 30 min run at 100 mph.

3 examples of 3 types of tread pattern:
|
The tread pattern changes across the face of the tire. Usually incorporates larger tread blocks on the outer portion for increased stability during cornering. The smaller inner blocks aid in dissipating water. |
 |
|
Designed to rotate in only one direction, unidirectional tires enhance straight-line acceleration by reducing rolling resistance. They also provide shorter stopping distance. Unidirectional tires must be dedicated to a specific side of the vehicle. Care must be taken when rotating unidirectional tires to ensure that the repositioned tire rotates in the correct direction. |
 |
|
Consistent across the tire's face. Both halves of the treadface are the same design. |

3 common types of tire construction:
Bias Ply- These tires have two, or more body plies which cross at an angle to the centerline of the tread and which strengthen both the sidewall and the tread area.
Bias Ply Belted- Steel belted variety of the Bias Ply.
Radial Ply- The body cords run across the tire perpendicular to the beads. Radial tires have belt plies which run nearly circumferentially around the tire, under the tread, to stabilize the tread, to strengthen the tread area and add flexibility to the sidewall. By restricting tread movement during contact with the road, the belt plies improve tread life. (Radial tires can also come with steel belts.)

3 major types of peanuts are grown in the American South and Southwest:
- Runners: Were introduced in the Seventies and are now the most popular type, are primarily made into peanut butter.
- Virginia peanuts: They are sold roasted in the shell.

3 basic types of brakes used on a roller coaster:
Check Brake- A safety device that allows more than two trains to be on the same circuit, as part of the "block" safety system.
Scarf Brake- Used only to slow down a train, and are usually pre-set.
Trim Brake- A brake used to slow the train running the track.
3 (or 2) train lengths of a flat stretch of track is used as a Brake Run at the station approach, where in-bound trains are halted. Since it is very difficult to stop a train with wet brakes, this area is usually covered to keep the brakes dry during a rainstorm.
A roller coaster car uses 3 different types of wheels:
- Guide Wheel- A set of wheels which guide the train so that it does not leave the track sideways (also known as Side-Friction wheels).
- Road Wheel- A wheel that actually rides on the top of the track.
- Upstop wheel- A set of wheels which ride underneath the track to keep the train from jumping off or leaving the trackwork (also referred to as "Undershot" or "Underside" Friction wheels).

3 tables of elemental elements:
The
first list shows elemental composition of the human body by weight, not including the trace elements:
manganese, zinc, copper, aluminum, cobalt, selenium, chromium, etc.:
|
| |
|
Oxygen--- Carbon--- Hydrogen--- Nitrogen--- Calcium--- Phosphorous--- Potassium--- Sulfur--- Sodium--- Chlorine--- Magnesium--- Iron--- Iodine--- |
65% 18% 10% 3% 1.5% 1.0% 0.35% 0.25% 0.15% 0.15% 0.05% 0.0004% 0.00004% |
Using hydrogen as a standard, the above table was converted into elemental composition by mole to reflect stoichiometry:
|
| |
|
Hydrogen--- Oxygen--- Carbon--- Nitrogen--- Calcium--- Phosphorus--- Potassium--- Sulfur--- Sodium--- Chlorine--- Magnesium--- Iron--- Iodine--- |
63% 26% 9% 1.25% 0.25% 0.19% 0.06% 0.06% 0.04% 0.025% 0.013% 0.00004% 0.000002% |
Then it was estimated that the human body is 72% water (an admittedly low estimate) and was removed from the original list, before recalculating the elemental composition by mole, dehydrated:
| By Mole, Dehydrated | |

Hydrogen--- Carbon--- Nitrogen--- Oxygen--- Calcium--- Phosphorus--- Potassium--- Sulfur--- Sodium--- Chlorine--- Magnesium--- Iron--- > Iodine--- |

3 common types of air-conditioning systems:
Room,- Room Air-conditioners typically sit in a window and the complete air conditioning system is contained in one box. This system is most suitable for one room only.
Split System,- This system can service more than one room. With the Split System, the compressor (which makes the most noise) is located outside the house and the evaporator is located inside.
Ducted,- is the best solution for air-conditioning a complete house or large areas. It provides maximum flexibility if you want different temperatures in rooms.

3 to 1 ratio of internet connections as of 04-13-02:
1 of 3- Dial up: Requires a modem. Is the most widely used means of internet connection because of its affordability to the average computer user but it provides the slowest transmission of information. It also ties up the phone line so that no calls can be received nor can a fax machine be used (Though there are computer programs which enable someone to send a fax using their computer.)
2 of 3- DSL (Digital Subscribers Link): DSL technology uses the same connection as your regular phone line, yet allows you to call and surf at the same time. This is possible because the DSL modem allows data transmission over your phone lines at far greater speeds than a traditional modem. You are also provided a dial-up account to use with a traditional modem when you are away from home.
3 of 3- Cable services: use the same coaxial cable connection as your cable T.V. Usually, the cable service provider simply hooks up your PC to a cable modem and you're ready to go. Plus, you can surf the Web and watch your cable programming simultaneously. The cost of DSL and cable are generally about the same.
1 of 1- Satellite: Usually, the service provider installs a satellite dish on or near your home and signals are sent to you just like a satellite T.V. Satellite is generally more costly than DSL and cable and also requires the use of your phone line.
http://www.compaq.com/athome/innovation1/mgced/2_hottopics_broadband.html
As of March 15, 2012, many homes have switched from using the common telephone line to the usage of a cable because of the desire for high speed data transmission and the increased reliance on cell phones. In some cases, an "Air Card" (connected via a cell phone service) is being used by those who want to be connected to the internet "On The Go," which is highly desirable for some business, motor home, camper, and other "auxiliary" mobile lifestyles.
