✦ Synopsis

A cost-effective torsional testing machine for sheep long bones was constructed. ?'he machine was fabricated on n d&used standard turning lathe. The angular speed used was 6.5"/s. A precision amplifier using modern low-noise, low-deft operational amplifiers was developed. The maximum torsional load was 250 Nm, the sensitivity 0.5 Nm and the total machine inaccuracy less than 1.0 %. The standard error of torsional testing was 3.0 % when smcn pairs of intact sheep tibiae were tested.

Thorough mechanical testing of rodent bones requires an understanding of bone behavior in a variety of loading modes including tension, compression, bending and shear. While these tests are easily conducted with single axis mechanical testing machines, it may also be desirable to determine torsional
