MODEL TESTING APPARATUS
The Department has apparatus for the determination of stresses in structural
and machine parts by the use of models.
The Beggs' Deformeter is a specialized set of equipment for the determination
of moments and shears in elastic structures by utilizing Maxwell's
principle of reciprocal deflections. The work is done on small scale models
accurately cut from celluloid or other suitable material.
This year the Department is securing modern Photoelastic equipment for
the analysis of stresses in elastic members. The equipment consists of an
elaborate optical set in which a model of bakelite is inserted. The method is
based on certain optical effects imposed on a ray of light by the stressed
model.
