B Speed of sound in steel at different temperatures?

Click For Summary
The discussion focuses on the relationship between the speed of sound in steel and temperature, highlighting the need for a formula to calculate this effect. A Google search revealed numerous resources on the topic, indicating significant interest and available information. An article from 1886 in Nature magazine titled "The Effect of Change of Temperature on the Velocity of Sound in Iron" is mentioned as a historical reference. Participants express curiosity about the specific calculations and variations in sound speed due to temperature changes. Understanding this relationship is crucial for applications involving steel in varying thermal conditions.

TL;DR
How to calculate speed of sound through steel in different temperatures?
Is there a formula to calculate the speed of propagation of sound waves through steel (a steel bar, for example) according to the temperature of steel?

I did a Google search on speed of sound in steel vs temperature and got lots of good hits (Google even finished typing the word "temperature" for me). Here is the hit list:

Thank you.

As a curiosity, an article named "The Effect of Change of Temperature on the Velocity of Sound in Iron" was published in Nature magazine on 22 April 1886:

Thread 'Why higher speeds need more power if backward force is the same?'

Thread 'Why higher speeds need more power if backward force is the same?'

Power = Force v Speed Power of my horse = 104kgx9.81m/s^2 x 0.732m/s = 1HP =746W Force/tension in rope stay the same if horse run at 0.73m/s or at 15m/s, so why then horse need to be more powerfull to pull at higher speed even if backward force at him(rope tension) stay the same? I understand that if I increase weight, it is hrader for horse to pull at higher speed because now is backward force increased, but don't understand why is harder to pull at higher speed if weight(backward force)...
