Why do some electricity pylons collapse in extreme temperatures ?

Click For Summary
SUMMARY

Electricity pylons can collapse in extreme temperatures due to the physical properties of the materials used in their construction and external environmental factors. High winds exert significant force on pylons, which may not be designed to withstand such conditions, leading to structural failure. Additionally, the accumulation of snow that turns to ice increases the weight on the pylons, further contributing to the risk of collapse. Understanding these dynamics is essential for addressing the vulnerabilities of electricity pylons in adverse weather conditions.

PREREQUISITES
  • Knowledge of basic physics principles, particularly forces and material properties.
  • Understanding of structural engineering concepts related to load-bearing structures.
  • Familiarity with the effects of temperature changes on materials.
  • Awareness of environmental factors such as wind speed and snow accumulation.
NEXT STEPS
  • Research the physics of material expansion and contraction due to temperature changes.
  • Study the impact of wind forces on structural integrity, focusing on engineering principles.
  • Examine case studies of electricity pylon failures in extreme weather conditions.
  • Explore design improvements for pylons to enhance resilience against environmental stressors.
USEFUL FOR

Students preparing for SQA National 5 Physics, physics educators, structural engineers, and professionals involved in the design and maintenance of electricity infrastructure.

Homework Statement



Using physics knowledge, why do some electricity pylons collapse in extreme temperatures.

Homework Equations


The Attempt at a Solution


Don't know the physics formulas or equations that could be used. High winds would force the pylons to collapse as the structure hasn't been made to withstand highwinds of extreme speeds. Also snow could fall on them turning to ice making them heavy and then collapsing. Not sure how to explain this in physics terms. answer is for 3 marks in SQA National 5 Physics (Scotland)

Thank you so much

Electric pylons and extreme weather

It is from the sqa specimen paper on the sqa website, but the answer states its open ended with no more hints.

Okay. Just checking.

Think about what materials make up pylons and what they are connected to. How do temperature changes affect those materials?
