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 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.
