The unwin formula is used to determine the size of the rivet. Unwin's formula gives a relation between hole diameter of rivet and thickness of the connected plates. The 'd' in the formula represents nominal diameter of the rivet in millimeters (mm) and 't' represents thickness of the plate in millimeters.
Hence, the correct option is (D)

Unwin's Formula
Unwin's formula states that the nominal diameter of a rivet (in mm) can be calculated as 6.01 times the square root of the thickness of the plate (in mm).

Calculation
Given that the thickness of the plate is represented by 't', the formula to determine the nominal diameter of the rivet is:
Nominal diameter = 6.01 * √t

Answer
Therefore, the correct answer is option D: 6.01√t. This formula is derived from empirical data and is commonly used in engineering practices for selecting appropriate rivet sizes based on plate thickness.
