Description

  • Rapson's Slide (Boat Rudder) Science Labs Features Low cost, effective teaching Self contained Easily seen from a distance Mechanism clearly understandable Loci drawn for further study Standard mechanism for operating the rudder of a boat 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 othes or whether a particular motion (such as a straight line) is developed. Description One 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 frame of the mechanism has a slot offset from a fixed pivot O.
  • A slider P in the slot carries a link pinned to it while the other end of the link slides in a turning block at O.
  • Hence a small effort at P will produce a large torque at O to drive the rudder of a boat.
  • 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.
