Why do some electricity pylons collapse in extreme temperatures ?

AI Thread Summary
Electricity pylons can collapse in extreme temperatures due to the physical properties of the materials used in their construction, which can be affected by temperature fluctuations. High winds can exacerbate structural weaknesses, leading to failure if the pylons are not designed to withstand such forces. Additionally, ice accumulation from snow can increase the weight on the pylons, contributing to their collapse. Understanding the impact of temperature and weather conditions on the materials and structural integrity is essential for explaining these failures in physics terms. This topic is relevant for SQA National 5 Physics assessments.

Homework Statement



Using physics knowlege, 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?

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
