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 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.
EXPERIMENTAL CONTENT
- Four-bar linkages – crank rocker, double rocker, drag link and parallelogram
- Determine degrees of freedom of a four-bar linkage
- Straight line linkages – Watt’s straight line, Chebyshev, Peaucellier- Lipkin, Hart’s inversor and Hoeken’s
- The different ways motion is transferred from one motion to another. For example, linear to rotary and linear to rocking
- The different motions scribed by different locations on a bar linkage system
- What is meant by constrained motion?
- Pantograph
- Ackermann steering
