The Archimedes principle states: The magnitude of the force equals the weight of the fluid that the object displaces. An alternative method of measuring the buoyancy force is to measure the amount of fluid displaced when the object is floating in the fluid tank. The level before and after immersion is monitored using the integral scale on the outside of the fluid tank. Test object shapes are solid cylinder, cube, sphere and cone are supplied as standard, there are also three identical shapes that are made from different materials, these are aluminium, brass and steel. The change in position of the counter weight gives rise to a reduced moment thus indicating the magnitude of the buoyancy force being applied to the object. Each test object is water proofed to avoid inaccuracies of results and corrosion over time. When the test objects are suspended the moment lever arm is brought to the horizontal by moving the balance hanger and monitoring the small spirit level until level. When the test object is lowered into the fluid the counterweight is adjusted to bring the moment lever arm back to the horizontal. The fluid tank can be filled with water or another medium, i.e. anti-freeze, oil etc. The samples attach to the moment lever arm using a cord and lowered into the fluid tank by lowering the cord accordingly, a scale on the lever arm allows the user to also record the amount of distance the shape has been lowered.

This is often seen in an ice skater performing a pirouette. First they spin round on an axis corresponding to their body, arms outstretched. When they raise their arms above their head, the increase in spin in considerable. Conservation of linear momentum is well understood and often demonstrated to students. Rather than go to an ice rink, students can perform this experiments in the laboratory. Equally important is the conservation of angular momentum. It is not easy to do meaningful experiments on this, but a highly visual demonstration of almost dramatic impact is the effect of reducing the radius of a rotating mass.
The resulting increase in angular velocity is considerable.
The weights are moved to the outer ends of their travel, away from the centre of rotation. The arm is then spun rapidly by hand, and the weights pulled towards the centre by the cord.
A bench mounted vertical board has a rotating arm along which two weights can be moved by a pull cord operated by the student or demonstrator.

The unit consists of a metallic base structure which provides the support locations for the structure. It has a spring balance which shows the elongation and hence the force acting on movable end due to the load applied on the top of the structure via a hanger. Three members are connected in a triangular shape to form a toggle joint. The base structure is fixed at one end but its other end is movable.
This unit is designed to study the characteristics of toggle joint. Toggle joint is a structure which has three members connected in a triangular shape. Its length can change due to the load applied at the top of the triangular structure. Two of its members have fixed lengths but third member (base member) has a variable length.
The unit has dial gauge attached to the upper end of the rubber block to measure the amount of deformation. The unit consists of a frame that is attached to wall.
