Which of the following requires more space for the rotation of spanner...
Explanation: Angle of rotation for hexagonal head is one sixth of a revolution to enable the next pair of flats to be engaged while it is one fourth of a revolution in case of square head.

Which of the following requires more space for the rotation of spanner...
Explanation:
To understand why a square head spanner requires more space for rotation compared to a hexagonal head spanner, we need to consider the geometry and design of both types of heads.
Square Head:
A square head spanner has four sides, each forming a right angle. When using a square head spanner, the user needs to rotate it by 90 degrees to engage with the fastener. This means that for every complete rotation of the fastener, the spanner needs to be turned four times. The spanner must be completely disengaged from the fastener after each 90-degree rotation and repositioned for the next turn. This requires additional space for movement.
Hexagonal Head:
A hexagonal head spanner, on the other hand, has six sides, each forming an angle of 120 degrees. Due to the design of a hexagonal head, it provides a more efficient engagement with the fastener. For every complete rotation of the fastener, the spanner only needs to be turned three times. The spanner can remain engaged with the fastener throughout the rotation, eliminating the need for complete disengagement and repositioning after each turn. This results in less space required for rotation compared to a square head spanner.
Conclusion:
In summary, a square head spanner requires more space for rotation because it needs to be fully disengaged and repositioned after every 90-degree turn. In contrast, a hexagonal head spanner can remain engaged with the fastener throughout the rotation, resulting in a more efficient use of space. Therefore, the correct answer is option 'A' - Square Head.
