Last month we acquainted you with a few unique procedures for using conventional tune-up devices—such as a vacuum gauge, timing light and electrical analyzer—for evaluating the efficiency and ...

Horsepower and torque are all about cylinder pressure. Compression ratio, cam timing, cylinder head flow, and all the rest of the goodies that go into an engine aren't worth much if what enters the ...

If your vehicle has been running roughly or seems to be losing power, it's possible that there's a lack of pressure in one or more of the cylinders. Without enough pressure, the fuel/air mixture doesn ...

Defects can occur naturally during composite fabrication, and damage can be induced by impacts in service, but these tend to be relatively uncontrolled events. It was desired to induce an easily ...

I noted in a 2005 column (see "Current compression test methods" under “Editor's Pick,” at top right) that there are three basic methods of loading a composite material test specimen in compression: ...
