The Stress-Opticon is a unique, textbook size
instrument which can be used to demonstrate the
fundamental principles of stress analysis, mechanics
of materials and the general nature of stress
distribution in various structural shapes. Its five
movable loading screws allow an infinite variety of
loading modes - e.g., cantilever bending, column,
statically indeterminate beam, and eccentrically
loaded column to be studied on a single prismatic
model.
Each of the eight models available for the
Stress-Opticon is a separate structural shape which
can be easily correlated to standard textbook
examples.
The Stress-Opticon is effective in room lighting,
requiring no special light source. For lecture
purposes, it can be used with an overhead projector
for particularly dramatic presentations. In addition,
it is lightweight, yet rugged enough to be passed
from student to student during laboratory courses.
The Stress-Opticon is 9 in (229 mm) long, 6 in (150
mm) high and 1-1 /2 in (38 mm) deep. The device comes
complete with a detailed instruction manual and
structural Model No. M-241.
Each Stress-Opticon model is a specific structural
shape which can be subjected to a variety of
different loading arrangements. The models are
machined from Type PSM-1 Plastic, a durable,
non-brittle photoelastic material that is high in
photoelastic sensitivity and free from time-edge
effects. |
