Answer 1

Answer:

A

Explanation:

Answer 2

The correct answer is option (Α) πε.

Explanation:

• Geometrical moment of inertia of beam of circular cross-section of radius r is πε.
• The second moment of area, or second area moment, or quadratic moment of area and also known as the area moment of inertia.
• It is a geometrical property.
• Hence, the correct answer is option A i.e πε.
