The kit contains all the parts required to assemble a functional lever shears. The graphic symbolises standard and production parts, and represents fixed and moving connections differently. All parts are precision-manufactured on CNC machines and feature standard engineering tolerances and surface finishes. The parts are clearly laid out on a base plate. They are grouped into individual assembly sequences. The base plate is covered with a transparent cover panel on which a graphical representation of the assembly structure is printed. Multiple trays are stackable, providing for space-saving storage. The surfaces of the finished parts have a gunmetal finish to prevent corrosion.

Tilting Flow Channel is done by dropping a particle into a vertical liquid column and timing its fall between two points. Various sizes and density of particles are supplied including stream lined shaped objects. The Tilting Flow Channel apparatus is designed to study the drag of a particle in a liquid under various Reynold numbers. A guide at the top of the tube is provided to minimize disturbance to the liquid. A fluorescent tube light at the back of the liquid tube allows clear observation of the particle fall. Valves at the bottom of the tubes provide a mean for particle removal with minimum loss of the liquid.
Experiments:
Effect of boundary layer separation on motion of sphere.
Effect of particle shape on rate of fall and drag coefficient.
Measurement of drag coefficients of sphere under various Reynold numbers.
Exploration of dynamic similarity.
