alcoholic strength
6 qts of a 20% solution of alcohol are mixed with 4 qts of a 60% solution. What is the alcoholic strength?
dear answering community, i suck at math.
6*.2 + 4*.6 = X*10
1.2 + 2.4 = X*10
3.6 = X*10
.36 = X
36% solution
Your Barbaric Yawp = 12% More Strength
If you’ve seen the video of me lifting the Toyota you might have noticed the noise I make when I do maximum lifts. The fact is, I don’t think I could do a big lift like that if I had to be silent. First of all, it’s important to exhale during any heavy lifting – static contraction or otherwise – and although it’s possible to exhale silently, I’ve always preferred making a loud noise. I refer to this inarticulate grunt as a “Barbaric Yawp” in deference to the great poet Walt Whitman who wrote: “I sound my barbaric YAWP over the roofs of the world.”
While I certainly lack the grace and insight of a poet, it turns out I’m onto something. Back in 1960 physiologists Michio Ikai and Arthur Steinhaus published a study entitled Some Factors Modifying the Expression of Human Strength. They looked at some external factors that could affect a person’s strength performance. Basically they looked at a loud noise, the subject’s outcry (barbaric yawp), amphetamines, alcohol, adrenaline and hypnosis.
They sat a subject in a chair and fastened a cable to his wrist with a wide strap. When the second hand of a clock reach a given point the subject pulled against the cable in what amounted to a static contraction (isometric) biceps curl. Readings were taken from a tension meter connected to the cable.
The subjects given alcohol and adrenaline had improvements considered statistically insignificant. The most profound effect was from hypnosis where the subjects were given the suggestion of either feeling great strength or of great weakness. The subjects demonstrated either 26.5% more or 31.7% less strength while hypnotized. (That’s pretty amazing, but who has his own hypnotist?) Subjects given amphetamines saw a 13.5% improvement. Subjects who had a starter’s pistol (firing blanks) shot unexpectedly while lifting had a 7.4% increase in strength. And the subjects who shouted during their exercise garnered a 12.2% increase in strength.
Hypnosis: +26.5%
Amphetimines: +13.5%
Gus shot: + 7.4%
Yell: +12.2%
For most of us, having a personal hypnotist at the gym with us, taking amphetamines or firing a handgun during our leg press is just not going to be practical, to say the least. But the cheap and simple act of yelling your own barbaric yawp during your 5 second static exertion might well garner a 12.2% increase in your performance. Wow!
The researchers suggested that this phenomenon might be explained by acting to remove internal inhibitions. Somehow the Vikings must have known that when they ran ashore, bare-chested wielding battle axes and screaming their own, truly barbaric, yawp. But you can get the same benefit without the messy bloodshed.
