LABORATORY WORK IN STRENGTH OF MATERIALS.
The Sinclair Laboratory for work in Strength of Materials.—
This was founded on the original donation of Mrs. John Sinclair,
of New York City, as a memorial to her late husband. The collection
has since been considerably enlarged. It contains Riehle and
Olsen machines, each of 100,000 pounds capacity, arranged for tensile,
compressive, and transverse tests; an Olsen torsion machine of
50,000 inch-pounds capacity; an Olsen compression machine of 40,000
pounds capacity; a Ewing tester for the elasticity of rods; hand machines
for testing rods and wires under pull and small specimens of
timber and cast iron under transverse loads; Fairbanks and Olsen
cement testers of 1,000 pounds capacity each; apparatus for torsional
tests on both long wires and short wires; together with the necessary
accessory apparatus for utilizing these machines.
