Explanation: triangulation is by optical means. pacing is rough surveying. chaining gives almost accurate readings. taping gives accurate readings.
Explanation: it also transfers points from line ranger to the ground. spirit level is the instrument used to level the plane table by adjusting the spirit bubble in it to center.
Explanation: it generally consists of two laths, each of 1 yard or 1 m in length loosely tiered together. plumb bob is suspended at the center of the plane table to transfer the points on the plan to ground.
Explanation: plumb bob transfers points to the ground so it is used for centering. butt are used for measuring offsets.
Explanation: an interchangeable part is one that can be replaced with a similar part manufactured to the same drawing. it can be used in mass production with an economic oriented approach. assembly time decreases as mating parts are interchangeable.
Explanation: functional requirements are related to the function of a component that is what is required to do. interchangeability is for ease of replacement of part. economics is related to the minimum cost and time.
Explanation: for full interchangeability, only such machines are selected for manufacturing whose process capability ≤ manufacturing
Explanation: standardisation is important in interchangeability. it is essential to follow a common standard by all, only then interchangeability is possible. all standards used by the manufacturing unit are traceable to international standards.
Explanation: full interchangeability is also known as universal interchangeability. many times, universal interchangeability is not feasible because it requires machine capable of maintaining very high accuracy and high process capability.
Explanation: no. of groups segregated in selective assembly depends upon desired tolerance and process capability of machine. conditions like high quality and low cost can be achieved by selective assembly technique.
