To solve the question of drawing two different sets of block and tackle systems to obtain a mechanical advantage of four, we can follow these steps: ### Solution Steps: 1. **Understanding Mechanical Advantage (MA)**: - The mechanical advantage of a block and tackle system is defined as the ratio of the load lifted to the effort applied. To achieve an MA of 4, we need to ensure that the system has a configuration that allows this. 2. **First Set of Block and Tackle System**: ...
