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 Rihle 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; Fair-banks
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.
