In Visual Studio, you can draw a use case diagram to summarize who uses your application or system, and what they can do with it. To create a UML use case diagram, on the Architecture menu, click New UML or Layer Diagram.
The Benefits of Wheel Alignment. Proper wheel alignment is extremely important to protect tire investment and tire life, maximize fuel economy and stop safely in wet weather conditions. Proper wheel alignment helps vehicles hold the road better and feel more stable.
Turn a wheel at the rim and the force you apply (red arrow) is multiplied to give a bigger force at the axle (blue arrow). The bigger the wheel, the greater the effect, because the radius of the wheel works like a lever. The bigger the wheel, the longer the lever, and the more leverage you get. Turn the wheel at the center, instead, and it works the opposite way. Now the rim of the wheel goes further and faster. That's how you can use a bigger wheel to multiply speed.
