Question for people
Nov. 16th, 2004 09:51 amIs thermal mass equal to mass times a (units changing) constant? I.E. is the thermal mass of one 12 kg object equal to that of every other 12 kg object? I've asked a few people who I thought would know (chemical, civil, and mechanical engineers. No, I haven't been able to find a materials scientist.), and all of them said roughly "I think so. I mean, it sounds likely...."
Mind you I've forgotten why I cared in the first place, but care I do.
While we're on the subject of asking random questions; I don't understand what's going on with titanium in hammers and other impact tools (e.g. golf clubs).
I'm guessing that it's just marketing, but they're claiming that a similar sized Ti head will hit harder and be less work to swing. I believe that second part. I even believe that due to KE = 1/2mv^2 a titanium head will have more KE, but I think that inertia is the important thing here (by extrapolation to a dowel with a band of steel wrapped around the end to prevent splitting).
I can also see an advantage to a hammer that doesn't rust, and that doesn't get dinged up if you toss it into your tool box. Further, I think that giving Russia money right now is not a bad thing. I just don't really see a direct advantage for the hand holding the hammer.
Ideas? Comments?
