Question

Define the term obliquity in strength of materials

Answer 1

Obliquity in strength of materials:

• Obliquity is an astronomical term labeling the angle of tilt of the Earth's axis of rotation.  

• In technical terminology, it is the angle between the plane of the Earth's equator and the plane of the Earth's orbit around the Sun. The obliquity is about 23°27' but it is not fixed.

• The angle of obliquity is defined as the angle between the direction of the subsequent stress or force acting on a given plane and the normal to that plane'.

Answer 2

       Obliquity in strength of materials

• The term obliquity in strength it applies to area of reclamation.
• The angle between the "direction of the resultant stress" or force that acting on a plane and the normal to the respective plane.
• Obliquity is defined as astronomical term mentioning the "angle of tilt" in Earth's angle of rotation.
• In technical aspect, it is the angle formed between Earth's equator plane and the "plane of the Earth's orbit" around the Sun,
• And the angle that formed between "Earth's equator plane" and the  Earth's orbit plane is approximately equal to 23°27'.
