A force board is clamped into the working area of HST1 Universal Frame and Stand (sold separately). Single and double pulleys sets can be fixed round the perimeter of the HST1 to produce an infinite variety of multi-directional forces in a vertical plane.
By using a single cord ring (concurrent forces), up to six cords can be attached and the cords tensioned with load hangers and weights to obtain equilibrium.
The lines of action of the cords are transferred onto a sheet of paper (not supplied) clipped to the force board using the board clips provided. Two cord rings held together by a short cord are used for non-concurrent force experiments. The set of weights for the experiment is included.
A comprehensive instruction manual for lecturer and student, giving full details on apparatus assembly and operation as well as example results. All necessary assembly and operational tools are provided.
