Mechanics of Deformable Bodies Chapter 2 Thermal Strain Introduction (PH)

Bakit ang turo po samin baliktad, pag tumataas yung temp, nagcocompress daw po yung material. Pag bumababa daw po nag-eelongate?

Materials tend to expand when subjected to an increase in temperature. This phenomenon is known as thermal expansion. When a material is heated, the atoms or molecules that make up the material gain kinetic energy, causing them to vibrate more vigorously. This increased vibration leads to an increase in the average distance between atoms or molecules, resulting in an expansion of the material. (𝗦𝗼𝗿𝗿𝘆 𝗳𝗼𝗿 𝘁𝗵𝗲 𝘃𝗲𝗿𝘆 𝗹𝗮𝘁𝗲 𝗿𝗲𝗽𝗹𝘆.

Ano po ba formula gagamitin if same material at Cross section area tapos Ang given ay length Lang ng 3 rods at length ng beam at weigh ng beam? Paano po makukuha Ang stress po sir?

Hi. First of all, mahirap po iimagine ng sinasabi po ninyo ng walang complete paragraph of the problem and given figure. Pangalawa, ano pong stress tinutukoy po ninyo? P.S. Sorry for the very late reply, sobrang abala lang po sa work.
