Since the equation for calculating the circumference of a circle is simplypimultiplied by the circle's diameter, you can also calculate gear ratios by comparing two circles' diameters. Two gears, one with a diameter of 6 inches and another with a diameter of 3 inches, will have a gear ratio...
If both gears had the same diameter, they would rotate at the same speed but in opposite directions. Understanding the Concept of Gear Ratio Understanding the concept of the gear ratio is easy if you understand the concept of the circumference of a circle—the distance around the circle's ...
Said axle member or shaft 41 constitutes a driving shaft for the large sprockets, and for that purpose said shaft has at one end, outside the yoke flange and hoist brackets, a large gear 42 here shown substantially the same diameter as the large sprocket. Said gear is also fast with resp...
When an axle makes one complete turn, the tire it's connected to makes one complete revolution. But a tire with a larger diameter will travel farther than a wheel with a smaller diameter. That's because the distance a tire covers in one revolution is equal to its circumference. So a ...
Understanding the concept of the gear ratio is easy if you understand the concept of the circumference of a circle. Keep in mind that the circumference of a circle is equal to the diameter of the circle multiplied by pi (pi is equal to 3.14159...). Therefore, if you have a circle or...
As shown in FIGS. 5 and 6, the flange portion53protrudes from an upper end of the gear cover52to an outside in the radial direction of the imaginary circle centered on the axis O1, that is, to an outside of the outer gear50ain the radial direction. The flange portion53is fixed in...

I had a wire run out through the window, and placed on the roof all sorts of devices to constitute this capacity [shown in the diagrams as an elevated square]. The first step was to connect this alternator [shown in the diagrams as a circle] with one terminal to the water pipe system...
A pinball is a 1 1/16 inch diameter (about 3 cm) steel sphere that weighs 2.8 ounces (80 g). On a normal (unwaxed) table, the ball can reach speeds of up to 90 miles per hour (145 kph). With this traditional steel pinball, the ball's magnetic properties sometimes come into ...
