Class Set Mechanics 2.0

Investigate the laws of mechanics of solid bodies through experiments

Grade level: Grade 9 and above
Number of students: 12–18 students in 6 parallel groups of 2–3 students each
Use: Student experiments in small groups

With the Class Set Mechanics 2.0, students investigate fundamental laws of the mechanics of solid bodies through hands-on experiments. The set is designed for six groups working in parallel and covers key topics such as weight force, center of gravity and equilibrium, the laws of levers, as well as plastic and elastic deformation.

In seven experiments, students investigate one-sided and two-sided levers, Hooke’s law, weight force and gravitational field strength, as well as the behavior of leaf springs and sand during deformation. The included force meters allow measurements of up to 1 N. Experiments on the law of levers can also be extended to include torque.

The materials provide stable experimental setups and, according to the product description, can also be used outside a dedicated science laboratory if required. Comprehensive teacher materials support the preparation, implementation and evaluation of the experiments.

The experiments can also be linked to mathematics lessons. Topics listed on the product page include statistics, proportional relationships and an introduction to vector addition.

For additional experiments on fixed pulleys, movable pulleys and block and tackle systems, the Pulley Supplementary Set for Class Set Mechanics 2.0 (item no. 43022) can be used.

On the two-sided lever, the leverage law is clarified.


In the plastic deformation of sand, it is investigated whether the crater diameter generated when a steel ball falls into sand depends linearly on the fall height.


The use of a force gauge is learned when determining the weight force. The location factor is introduced or repeated. Finally, when comparing the measured values with theoretical values, the accuracy of the force gauge is discussed.


In this experiment, the elongation of a spring as a function of the force exerted on the spring is investigated.


The center of gravity, or more precisely a heavy axis, of an arbitrarily shaped disc is determined experimentally. Subsequently, the static equilibrium of the disk is examined.


On the one-sided lever, the leverage law is clarified.


In the elastic deformation of a leaf spring, it is investigated whether there is a linear relationship between the deflection of the leaf spring and the attacking force.
