Description
This
is a simple wall mounted apparatus supplied with three interchangeable
screw and nut assemblies. Load is applied to a weight hanger attached
directly to the screw and the effort torque is applied by a weighted
hanger and cord passing over a low friction ball bearing pulley.
This
equipment is part of a range designed to both demonstrate and
experimentally confirm basic engineering principles. Great care has been
given to each item so as to provide wide experimental scope without
unduly complicating or compromising the design. Each piece of apparatus
is self-contained and compact. Setting up time is minimal, and all
measurements are made with the simplest possible instrumentation, so
that the student involvement is purely with the engineering principles
being taught. A complete instruction manual is provided describing the
apparatus, its application, experimental procedure and typical test
results.
