Calculate deflection of rod/axlepipe due to distributed load

Click For Summary
SUMMARY

This discussion focuses on calculating the deformation of a rod, axle, or pipe subjected to a distributed load. The rod in question has an outer diameter of 62mm, an inner diameter of 50mm, and a length of 170mm, made from a material with an elastic modulus of 200 GPa and a Poisson's ratio of 0.3. The distributed load is 491 N/mm, and the second moment of inertia (I) has been calculated as 418536 mm4. The participants emphasize the importance of the type of support and the correct formula for determining rod deformation.

PREREQUISITES
  • Understanding of mechanical properties such as elastic modulus and Poisson's ratio
  • Knowledge of the second moment of inertia (I) and its significance in bending calculations
  • Familiarity with distributed loads and their effects on structural elements
  • Basic principles of structural engineering and mechanics of materials
NEXT STEPS
  • Research the formula for calculating deflection in beams and rods under distributed loads
  • Learn about different types of support conditions and their impact on deformation
  • Study the relationship between material properties and structural performance
  • Explore engineering textbooks or resources that cover mechanics of materials in depth
USEFUL FOR

Engineering students, structural analysts, and professionals involved in mechanical design or materials science who are interested in understanding the deformation behavior of rods and similar structures under load.

Summary:: Calculate the deformation on a rod/axle/pipe due to a distributed load.

I’m manually trying to calculate the deformation on a rod/axle/pipe due to a distributed load. The rod has an outer diameter of 62mm and an inner diameter of 50, is 170mm long, made from a material with an E-module=200GPa and Poisson's ratio = 0,3. The load is distributed along the whole length of the rod and is 491 N/mm. I have calculated the second moment of inertia I to be 418536mm^4, and I’m having no luck finding a formula for rod deformation/bending.

I have tried using this formula:

But i don't think it applies for rods, as my answer is low.

Is this question for your work or is it a schoolwork question?
 
Where did you get that equation from?
The type of support is very important.

From a Norwegian book for engineering. Posting a pic below.

For my bachelor thesis😁
 
Nice. I'll move it to the schoolwork forums then. :smile:
