Newall system of limits and fits is the oldest system working on hole ...
The correct answer is option 'A': 2 and 6.
The Newall system of limits and fits is one of the oldest and widely used systems for determining the tolerances of mating parts in mechanical engineering. It is based on a hole basis system, where the tolerances are specified for the holes rather than the shafts. In this system, the grades of holes and shafts are designated by a number, with lower numbers representing tighter tolerances.
Explanation:
The Newall system uses a combination of letters and numbers to specify the grades of holes and shafts. The letters represent the deviation of the hole or shaft from the basic size, while the numbers indicate the tolerance zone. The grades range from A to Z, with A being the tightest tolerance and Z being the loosest.
In the given question, the grades of holes and shafts specified are 2 and 6, respectively. This means that the holes are designated as grade 2, which corresponds to a medium tolerance zone, while the shafts are designated as grade 6, which corresponds to a loose tolerance zone.
The grades of holes and shafts in the Newall system are determined based on the intended fit between the mating parts. The fit can be categorized as clearance fit, interference fit, or transition fit. A clearance fit allows for a gap between the mating parts, an interference fit results in a tight or press fit, and a transition fit falls between the two.
In this case, the specified grades of 2 and 6 indicate a clearance fit, where the hole is slightly larger than the shaft. This allows for easy assembly and disassembly of the parts while still providing some degree of accuracy.
In summary, the Newall system of limits and fits is an established system for specifying the tolerances of mating parts. The grades of holes and shafts are represented by letters and numbers, with lower numbers indicating tighter tolerances. In the given question, the specified grades of 2 and 6 correspond to a clearance fit between the mating parts.
