Description
This
simple screw jack is a 220 mm diameter turntable fitted with a 30 mm x 6
mm pitch screw is supported in a heavy cast iron base. The apparatus is
stood on a firm bench and a cord and weight hanger are wound round the
rim of the turntable and hung over the pulley. The pulley runs on ball
bearings to reduce friction to a minimum.
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.
