1.		Fundamentals Of Statics Apparatus
Description:
The unit allows the fundamentals of Statics, such as equilibrium, force resolution, the principles of levers, and similar issues to be clearly demonstrated.
The base unit is a freestanding mounting board. All the parts necessary for the experiment can be quickly attached to the rails that are attached to the edge of the board. The printed perimeter grid enables structures to be accurately assembled.
Two large board straps allow the mounting of the individual experiment components. Each strap has equi-spaced threaded holes to allow mounting positions to be varied widely.
Two ball bearings facilitate low friction torque experiments. All forces measured using analogue spring balances.
The individual parts are supplied in a storage case.

2.		Work done by a Variable Force (Combined Vertical & tangential)
Description:
The apparatus is a simple lifting mechanism with obvious non linear characteristics.
A suspension cord carrying a loaded trolley at mid span is tensioned by passing the cord over a pulley at one end and down to a weight hanger. 
As the vertical effort is increased, the tensioned cord will move to a new equilibrium position lifting the loaded trolley. Heights of the load and effort are measured relative to the base. 
All the pulleys are fitted with ball bearings to minimise friction effects. 
A pivoted arm carrying a load hanger at its end is restrained by a spring balance at right angles to the arm. The angular position of the arm is indicated by a protractor scale attached to the back board. The effort is the force needed to hold the weighted arm at a particular angle. 
The back board easily sits onto a bench and each side of the board is used for the individual elements of the experiment, i.e. vertical on one side and tangential on the other.

5.		Fletchers Trolley
Description:
This apparatus consists up of an aluminum profiled base forms the track onto which a wooden trolley runs. The trolley has three precision bearings at its wheels and is pulled along the track by a set of weights and a load hanger.
A cord attaches the load hanger to the front of the trolley and the cord itself passes over a pulley with integral precision bearing to remove as much friction as possible.
The trolley has a number of key areas. On the top of the trolley is a long, smooth surface onto which paper is attached (via clips) to allow the acceleration traces to be drawn. Underneath the top surface is an area that locates the five (5) movable weights, each of 500g. At the rear of the trolley is another location that houses smaller weights. 
At the rear of the base is a structure that holds the horizontal vibrating arm. 
This arm has been tuned to oscillate at around 5Hz. At the tip of the arm is a fine tipped brush. The tip travels across the surface of the paper during a test and draws a sinusoidal trace using the ink provided. 
The height and pressure of the brush is fully adjustable. 
The vibrating arm is triggered automatically when the trolley starts to run along the base. 
There are many variables that the end user can adjust during testing. These include trolley weight, towing force, distance travelled. A bump stop slows the trolley after it has run the length of the track. 
Unlike other apparatus that have two points to measure acceleration over, this apparatus allows a full travel trace to be created. This then allows any variations in the acceleration of the trolley to be clearly observed.

Description:
A simple but elegant demonstration of the conditions of equilibrium for three or more coplanar forces acting either at a point, on a circular disc or on a rectangular shape. Up to five loads can be applied to the chosen shape by setting up pulleys at various angular positions. The lines of action of the forces are recorded by drawing along the weighted cords onto a piece of paper attached to the pulley table. The loads are applied using the hangers and cords provided, with the cords easily connecting to the shapes by the use of the small hooks provided. A range of experiments is possible, investigating concurrent and non-concurrent coplanar forces acting on simple shapes, comparing the experimental values with the relevant polygons of force.

7.		Wall Jib Crane Apparatus
Description:
This apparatus illustrates the application of a triangle of forces very clearly through the use of a wall jib crane.
This wall mounted self-contained jib crane has a vertical back support that supports a vertical rod. At the bottom of this rod is attached a swivel joint for the lower compression member. This joint swivels but cannot move vertically. At the upper end of the rod is a movable joint. This joint has a hook protruding and allows the attachment of a chain which itself is attached to the tension member of the crane.
The ends of the compression and tension member are joined at a common point. A small pulley is attached at this point also, over which a cord passes, and terminates with the load hanger. One end of the cord also attaches to a movable hook that runs vertically on the support rod.
By adjusting the cord length, chain length and positions of the hooks, the lengths of compression and tension members can be adjusted along with their angular positions.
The forces in the compression member are read directly from the integral Newton scale. A compression spring of known spring rate is enclosed within the compression member. A spring balance is suspended between the chain and the pulley to measure the tensile forces in the tension member. After loading the member lengths can be adjusted to their ‘zero load’ lengths as part of the experimental procedure
Technical characteristic:
•	Maximum vertical distance between wall pivots approximately 350mm
•	Tensile Member length approximately 500mm
•	Compressive Member length approximately 400mm

8.		Basic Roof Truss
Description
The basic roof truss consists of two rafters or struts and a restraining tie. Both rafters are pivoted at their apex.
The other end of one of the rafters is pivoted to a free standing base, whilst the remaining rafter end runs on ball bearings along a track.
When a load is hung from the apex, the free end of the rafter moves sideways, restrained by a spring balance tie.
Both rafters also include spring balances so that all internal loads can be directly measured.
Re-adjustment of the geometry back to its original unloaded configuration is easily made before taking measurements. The length of the tie can be varied to change the angles of the truss.

9.		Friction on an Inclined Plane
Description
The compact bench top unit has a sturdy aluminum base plate, non-slip feet and central vertical pillar. 
Pivoting on this base is a ground steel plane which can be locked in any angular position between ±45°, indicated on a semi-circular protractor scale.
