Peaucellier Straight Line Motion.
Peaucellier Straight Line Motion Science LabsOne of sixteen mechanisms
built on an A3 board equally suitable for the classroom, drawing office
or laboratory. The principal components are made from amber coloured
Perspex, pivoted with hollow rivets, and mounted on a white melamine
board for contrast and visibility. To see the mechanisms move is far
more instructive and convincing than listening to a static lecture. The
hollow rivets accept a pencil for transferring the loci of the joints to
a sheet of paper, clipped to the board.
The exact straight line produced by this set of eight links is achieved
by the geometry of the mechanism. ABCD is a rhombus with four equal
sides. Points O and P are fixed pivots while OP = OC. A is moved in a
straight line as OC rotates.
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.
Each mechanism is supplied with a manual which gives full instructions
for producing the loci and applications of the assembly. The typical
graphical result is appended.
Features:
Low cost, effective teaching
Self contained
Easily seen from a distance
Mechanism clearly understandable
Loci drawn for further study
Standard mechanism for generating a straight line
Three year warranty
Range of Experiments
To determine the loci of the moving parts of the standard mechanism
To establish the characteristics of that mechanism: for example to see
which links move faster than other or whether a particular motion (such
as a straight line) is developed.
