When you move a mechanical mouse the roller ball transfers it's movement to two slotted?

When you move a mechanical (computer) mouse, the roller ball transfers its movement to two slotted encoder wheels that have two sensors that detect the position of the wheels. The sensors are mounted an odd half number of teeth apart, giving two pairs of pulse trains that are 90 degrees out of phase with respect to each other. Running these pulse trains through logic comprising some XOR gates and a flip-flip, you can drive an up/down counter in such a way that the count represents the horizontal or vertical position of the roller. At the point where a change is detected, either by a movement of the roller or a change in status of a button, a message is sent to the computer that includes the button status and the delta-x and delta-y of the roller since the last update. The computer driver then integrates that into mouse messages that drive (typically) windows.

How the energy transfers determine the heights of the hills on a roller coaster?
the higher the hill the greater the energy transfers.
What type of scientist makes roller coasters?
Roller coasters are designed by mechanical engineers, not scientists.
Does your 2005 4.8 vortec have a mechanical roller tappet or a hydraulic roller tappet?
That would be a hydraulic roller tappet valve train.
How much money does a roller coaster designer make?
Roller coasters are designed by engineers. Roller coaster engineers make anywhere between $45,000 and $119,000 per year. Most roller coaster engineers are mechanical engineers and the median salary for mechanical engineers is $74,920.
How does the energy transfers determine the heights of the hills on roller coasters?
If they are high they go faster
How much mechanical energy is at the top of a roller coaster?
It depends on the roller coaster's height,speed,and location. :p
Where is mechanical energy on a roller coaster?
Mechanical energy is used on the chains that pull the roller coaster cars up the tallest incline, which is typically located at the start of the track. Mechanical energy is also used in the braking system that slows the cars to a stop at the end of the track.
What are energy conversions on a roller coaster?
electrical energy to sound, mechanical energy
Do roller coaster engineers have a civil or mechanical engineering degree?
That will depend on which part of the roller coaster you're talking about. The moving parts (the cars and the driving mechanisms etc) will be designed by a mechanical engineer. The structure of the roller coaster itself (the towers and trackway and the foundations on which it stands) will be designed by a civil engineer.
What are the main energy transfers that happen as a roller coaster cart travels along the track fromthe start of the ride to the end?
Basically the main energy transfers in a Roller Coasters are, Gravitational Potential Energy (PE), Kinetic Energy (KE) and some energy is lost through Heat and Sound.
Who builds roller coasters?
Engineering and architecture. You need to be able to understand a lot about roller coasters and how to design and build them.
The conversion of potential energy to kinetic energy demonstrates the what?
mechanical energy
