When the nature of contact between the elements of a pair is such that...
Explanation:
A pair is a combination of two links or elements which are connected in such a way that they have relative motion. The nature of contact between the elements of a pair determines the type of pair. There are four fundamental types of pairs: sliding pair, turning pair, rolling pair, and spherical pair.
Sliding Pair:
When the nature of contact between the elements of a pair is such that it can only slide relative to the other, the pair is known as a sliding pair. In a sliding pair, one element slides or reciprocates over the other element. This type of pair is also known as a prismatic pair. The sliding pair is the simplest form of a pair and is generally used in machine tools, jigs, and fixtures.
Examples of Sliding Pair:
1. Piston and cylinder
2. Sliding block and guide way
3. Sliding pair in a lathe machine
Advantages of Sliding Pair:
1. Simple and easy to manufacture
2. Requires low maintenance
3. High accuracy and precision
4. Can be used in both linear and rotary motion.
Disadvantages of Sliding Pair:
1. Frictional loss due to sliding
2. Wear and tear of the sliding surfaces
3. Requires lubrication to reduce frictional loss.
Conclusion:
In conclusion, a sliding pair is a pair of elements that can only slide relative to each other. It is a simple and easy-to-manufacture type of pair. However, it has some disadvantages like frictional loss and wear and tear of sliding surfaces. Sliding pairs are widely used in machine tools, jigs, and fixtures.
