EF-2.3 – Dynamics – Rotational Friction
The EF-2.3- Rotational Friction experiments kit enables students to understand rotational friction of a screw jack, a wedge and different bearings
Description
The Engineering Fundamentals range enables students to gain an understanding of the principles of engineering by the process of learning via experimentation.
The EF-2.3- Rotational Friction experiments kit enables students to understand how rotational friction affects the efficiency of a screw jack, a wedge and different bearings
The kit includes experiments that measure the effort required to raise various loads using a simple form of screw jack.
These include determining how the mechanical advantage and efficiency varies with load, the mechanical advantage and efficiency obtained by using two different wedges including investigating the effect of the angle on overhauling and to compare the resistance to rotation due to friction in four cantilevered bearings of different materials.
Engineering fundamentals system
The modular tray-based system is supplied in conjunction with a multifunctional work panel enabling the student to conduct their own experiments in subjects such as statics, dynamics, mechanisms and kinematics.
Each kit is supplied with a highly visual user-friendly operational guide, allowing the student to understand the theory of the subject by the application of practical experimentation.
