Force Table


Force Table



For performing static force experiments in mechanics such as studying the condition of static equilibrium of a rigid body under the action of forces in a common plane i.e. for the verification of the laws of composition and resolution of forces. Can also be turned into a teaching spectrometer by using appropriate collimator assembly, telescope and a support for prism and grating.

Comprised of an accurately machined aluminium table 40cm in diameter graduated in 360° on its rim. Mounted on a heavy vertical support rod and tripod base fitted with levelling screws. Body under study is a ring in the centre of the table fastened by strings passing over four low friction pulleys attached with the table. Provided with four weight hangers of 50g each and four sets of brass slotted weights (each set consists of the masses: 2 x 10g, 2 x 20g, 4 x 50g, 4 x 100g).

Boyle S Law Apparatus


Boyle S Law Apparatus

Item Code: 3548-21

Apparatus for the recording of pressure verses volumes and for investigating boyle’s law. The vertical tube is part – filled with the colored liquid and sealed. The trapped air is then compressed progressively, with pressure (p) and volume (v) readings taken at each stage. Before each pair of readings is taken, the liquid should be allowed to settle so that the heat caused by the compressions is dissipated. The air is trapped in a long, graduated vertical tube. This scale is in arbitrary units. These can be taken as indicating the volume of the trapped air. Pressure is applied by using a bicycle pump (or similar) and can be read off the gauge provide. This gauge is calibrated this gauge is calibrated in both kg/cm and p. S. I. A reservoir under the gauge ensures that the pressure reaching the trapped air does not fluctuate too violently. The vertical tube will withstand the pressures required for the demonstration. However replacement of the bicycle pump with a foot pump might result in pressures greater than the apparatus can stand.
