EF-3.4 – Mechanisms – Bar Linkages
The EF-3.4- Bar Linkages experiments kit comprises of different perforated bars or links configured into a range of different linkage mechanisms
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-3.4- Bar Linkages experiments kit comprises of different perforated bars or links configured into a range of different linkage mechanisms, including four-bar linkages, rotary and linear movement and planar linkages allowing students to trace the relative movements of each linkage and joint.
A linkage is an assembly of links and joints that provide a desired output motion in response to a specified input motion.
One such example and one of the simplest moveable closed-chain linkages is the four-bar which consists of four bars or links connected in a loop by four joints and can be used for many mechanical purposes including converting rotational motion to reciprocating motion and converting reciprocation motion to rotational motion.
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.
