Concrete block weighing 20,000 lb is supported by 2 STEEL rods

Click For Summary
SUMMARY

The discussion centers on calculating the elongation of two steel rods supporting a concrete block weighing 20,000 lb. Rod AB has a cross-sectional area of 1 in², while rod CD has an area of 2 in². Participants emphasize the importance of first determining the reactions of the steel rods on the concrete block to proceed with the elongation calculations. The user ultimately finds the answer after engaging with the forum.

PREREQUISITES
  • Understanding of static equilibrium principles
  • Knowledge of material properties of steel
  • Familiarity with stress and strain calculations
  • Basic proficiency in mechanics of materials
NEXT STEPS
  • Study the principles of static equilibrium in structural analysis
  • Learn about stress-strain relationships in materials, particularly steel
  • Explore elongation calculations using the formula for axial deformation
  • Investigate the effects of cross-sectional area on load distribution in structural members
USEFUL FOR

Structural engineers, mechanical engineers, and students studying mechanics of materials will benefit from this discussion, particularly those focusing on load-bearing structures and material deformation analysis.

what is the elongation of each rod...?

i don't know how to start, should i take reactions of the concrete block??

any help will be appreciated.
Finding reactions of the steel rods on the concrete block would be a good start. Can you find them? Then what?
 


wooo thanks i found the answer !
