In a building the column of concrete is 2 metres long and is used to resist a load of 200 MN. during the day there is a rise in temperature in the column from 25 degrees Celsius to 42 degrees celsius assume the thermal coefficient of linear expansion of concrete is 1.45 x 10 ^ -5 degrees Celsius the area of the column which the load sits is 0.07 m square the modulus of elasticity is 220 GPa​ determine the strain that will occur in the rod due to the temp change
find the change in length of the rod due to compressive forces
what is the change in the length of the rod due to the change in temperature

can you explain it better

glass wants to live in a world of super heroes and villains. he have lived all his life trying to be responsible for the creating the origin story of a super hero; he schemed and caused many incidents (many of them fatal) hoping that someday someone with superpowers would show up and save the day.

he knew himself very much. he saw himself as a villain of a real-life super hero story. he was aware of his strengths (more than smart enough for being manipulative and scheming) and weaknesses (having fragile bones and having to rely on his mind to succeed).

answer; ///he could not explain why the continents drifted;
