Magnetic Black Board

Magnetic Black Board

The Magnetic Black Board is a unique magnetic mount system where dynamics diagrams are transformed into working demonstrations. This black board demonstration system illustrates in a unique way mechanical equilibrium, inclined planes, levers, pulley systems, simple machines and much more. You can also easily attach various springs, weights and scales and perform interesting experiments with ease and accuracy.

In order to truly understand the meaning to the sentence “the magnitude of the force F1 is two to three times higher than that of force F2”, it is necessary to have a method for comparing the magnitude of the two forces. One method is to measure the magnitude of one of the two forces and assume the other to be a known reference force.

We can estimated Hooke’s constant using a spring, a magnetic ruler and masses of different values. Each different spring will have its own Hooke’s constant value and this value is directly proportional to how difficult it is to stretch the spring.

Therefore by measuring the rate of stretch (or elongation) of the spring exerted on it by gravity, we can estimate (using the slope of the graph) the elastic constant of the spring.

The Altay Magnetic Black Board give teachers and students the freedom to set up experiments with their own fashion. Thanks to the magnetic pins it’s easy to place the inclined plane, pulleys, and all the other objects everywhere on the board and perform experiments in any configuration.

The accessory case contains also multiple in – line and in – axis pulleys to study the mechanical advantage of a system of pulleys like the block and tackle as in the particular configuration of the triple – in – line pulley block.
