>Thanks, Ron; I guess I did think titanium was stronger. So it depends >whether you measure by volume or by weight... The modulus of elasticity of titanium is somewhat less than half that of steel, so for a titanium bar to have the same stiffness as a steel bar 1" in diameter, it would have to be 1.2" in diameter, or thereabouts, but would weigh only 80% what the steel does. With the titanium bar at a bit over 1.3", it would weigh the same as the steel, but be about 35% stiffer. Some more of life's little trade-offs. Ron N
