Washers are ubiquitous and integral components of any mechanical and engineering system. Any system that has moving parts that create friction and wear and tear require washers to maintain the integrity of the system. The primary purpose of washers is to reduce friction, prevent damage, and enhance the lifespan of parts.
It is vital that students studying mechanical and engineering systems understand the importance of washers, how they function, and where they are used. A lot of the practical applications of the knowledge they gain will help them in constructing machines and equipment that function properly.
One way to introduce students to the purpose of washers is by explaining how they work and the various types that exist. This includes flat washers, lock washers, split washers, spherical washers, and spring washers. Each type has specific uses depending on the mechanical system in which they are employed. For instance, flat washers are used to distribute the load of a bolt or nut, while lock washers are used to prevent the rotation of a bolt.
Students should also learn the importance of selecting the correct size and thickness of washers. Inadequate washing sizing can result in the bolt or nut not being tightened enough, increasing the chances of them coming loose. Additionally, incorrect washer thickness can result in the bolt being overtightened, causing permanent damage to the nuts or bolts.
Another aspect of teaching students about the purpose of washers is to make them understand how washers can be used to solve problems in mechanical and engineering systems. This involves demonstrating examples of how washers come in handy when a mechanical part is damaged, or a nut or bolt is missing.
In conclusion, teaching students about the purpose of washers can be a fun and informative exercise that can help them understand how mechanical systems work. Understanding the function of washers, how they work, and where they come in handy can help students better appreciate the complexity of machines and more fully comprehend their practical uses. With an in-depth understanding of washers, students will be equipped to design and construct mechanical systems with greater efficiency and precision.
