BTec Engineering - Efficiency and mechanical advantage (PowerPoint)
This is a 12 slide PowerPoint that covers BTec National Engineering (A-Level equivalent) on the topic of Efficiency and Mechanical Advantage as applied to lifting machines in engineering.
This is the seventh PowerPoint in this section which covers Mechanical Advantage and Velocity Ratio in ideal systems and then applies this to non-perfect scenarios so that efficiency can be calculated. The lifting machine of a block being pushed up a slope is used throughout this PowerPoint to cover this topic in an easy to understand manner. This is extended to more complex listing machines in the next PowerPoint in the series.
