In a car, there are four wheels that move in a speacial manner. These wheels are called the front, rear, swingarm, and gearbox. Each of these parts can change the speed of your car.
The front wheel is called the normal wheel and the rear wheel is called the disabledwheel. The swingarm is considered the thirdwheel. The fourth and final rotating part of your car is the gearbox.
This part of your car can be considered the transmission and how it changes speed of your vehicle. The Figure 1 Shows A Car With Four Rotating Wheels. For Each, Determine The Signs (+ or -)Of Ω And Α.
When determining whether an element exists or not, determining its signs is key.
ω1 = -ω2
The first figure shows a simple rotating wheel with only four wheels. The rotating wheel has a central disk, which is offset from the other three disks by an angle.
The angle must be acute (90 degrees or 0-90 degrees), as shown. This rotating wheel would be called an acute-angled rotational disk.
The other three disks must be parallel to the central disk, and they must rotate at the same speed as the central disk. These other three disks are referred to as subrotating disks.
Figure 1: An acute-angled rotational disk with four subrotating disks.
ω3 = -ω4
When a toy has four rotating wheels, the designer must determine which two wheels will be Ω and which two will be Α.
Figure 1: The designer made two of the rotating wheels Ω and two of the others. This is a sign (+) of Ω because one can choose which two wheels to play with.
Figure 1: The second difference between these toys is how each player chooses to rotate their wheel. The one in blue chooses to spin faster, while the one in green chooses to take their time more slowly. These differences are signs (-).
Bullet point: Both Make a noise When played with.
none of these combinations are true
If you were to build an Ω or an Α, your combination would be impossible to reverse. These combinations are created when two or more axes are matched up together and then rotated.
The rotational axes must match up in order for the combination to work. If one of the axes was rotated away from the others, then the combination wouldn’t work.
However, if one of the other axes was rotated into place, then a new configuration could be built with them. This is why it is called a configuration-raising combination.
The four rotating wheels in figure 1 show different configurations that can be built with this figure 1 combination. Figure 2 shows one of these combinations in action.
