Question

Which among the following criteria is used for describing shape of an object?

(A) Roundness

(B) Sphericity

(C) Charted standards

(D) Resemblance of geometric bodies

Choose the correct answer from the options given below:

• A. (A) and (B) only.
• B. (A), (B) and (D) only.
• C. (A), (B) and (C) only.
• D. (A), (B), (C) and (D).

Hint:

Recall the different qualitative and quantitative methods used together to describe shape in physical properties of produce.

Answer 1

The Correct Option is D

Step 1: When describing the physical shape of agricultural produce, engineers use several complementary methods, not just one number, because a single figure rarely captures shape completely.

Step 2: Roundness describes how sharp or blunt the corners of an object are, it compares the radius of curvature of the sharpest edge with the radius of the largest inscribed circle of the object's outline.

Step 3: Sphericity describes how close the overall body is to a true sphere, usually expressed as the ratio of the diameter of a sphere of the same volume to the diameter of the smallest circumscribing sphere (or an equivalent ratio of the three principal dimensions).

Step 4: Comparison with charted standards means visually matching the produce's outline against a printed reference chart of standard shape silhouettes, a quick practical method used in grading.

Step 5: Describing resemblance to geometric bodies means classifying produce as round, oblong, ellipsoidal, conical, and so on, by comparing it with familiar regular solids.

Since all four, (A), (B), (C) and (D), are recognised, standard ways of describing shape, the correct answer is option 4.
