Questions & Answers

Q: What is the limit of eccentricity for a circular section with a diameter of 50mm?

The limit of eccentricity is calculated as 6.25mm for both the x and y directions.

Q: How is the limit of eccentricity determined for circular sections?

The limit of eccentricity is determined by finding the section modulus and area of the circular section and applying the no tension condition.

Q: What is the significance of the limit of eccentricity?

The limit of eccentricity represents the distance from the center of a circular section where a load can be placed without causing tension, resulting in a fixed section.

Q: How is the section modulus of a circular section calculated?

The section modulus for a circular section is calculated as pi/32 times the cube of the diameter.
