As a retired automotive engineer, I enjoy reading your column. Your recent column about a '92 Ford Tempo caught my attention. Your handling of the explanation of what a "harmonic balancer" is was well done because technical terms like "outboard balance" and "crankshaft torsional harmonics" were neatly sidestepped. There was one lapse, however. You said "there's a rubber sleeve that dampens crankshaft vibrations." It is the word "dampens" that caught my eye, because there is no water or liquid associated with the damper. I can still envision my professor demonstrating the difference between "damps" and "dampens." To demonstrate "damp," he bounced a ball, and then stopped it from bouncing. He demonstrated "dampens" by filling a salt shaker with water and then pouring it on his lectern. If I didn't learn anything else, that demonstration stuck. -- Warren
TOM: Warren, you are 100 percent correct.
RAY: We'll give ourselves 40 lashes with a damped noodle.
TOM: DAMPENED noodle!
