    The advancement of research in new engineering materials has led to the development of magnesium metal matrix composites (Mg MMCs). This study critically examined the production techniques, properties, and applications of Mg MCs. Powder metallurgy and casting routes were the two classifications of the techniques for producing Mg MMCs. The mechanical, tribological, corrosion, and bio-compatibility properties of the composites and the application of the Mg MMCs were reviewed. Orowan strengthening mechanism, Hall Petch strengthening mechanism, and Taylor strengthening mechanism were the mechanisms responsible for the improvement of the strength of the composite. The study further highlighted the areas for future studies.

    Slider-crank mechanism (SCM) was developed with digital read-outs in this study to make the reading of experimental results more accurate. They are connected by joints and force elements for the conversion of reciprocating motion into rotary motion or vice-versa. A digital protractor (accuracy = ±𝟎. 𝟐) and a digital vernier caliper (accuracy = +0.02 mm) were incorporated as the crank and the slider respectively, while a stainless-steel plate was made the connecting link. The deviation of the slider (displacement) values from the corresponding theoretical values at various angles was determined. The simple harmonic ratio of the analogue mechanism is higher than that of the digital mechanism but the deviations of the slider (displacement) values of the digital mechanism from the theoretical values are quite negligible. The deviations of the analogue system from its corresponding theoretical values are far higher. Based on the result obtained, the digital system is more precise and accurate for experimental studies than the analogue system.
