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

    racial conflict and discrimination has existed ever since man learned to kill with rocks and bones. these conflicts arose from disputes between territory, power, wealth, religion, or simple difference. some of the most infamous racial disputes include slavery, the holocaust, and the civil rights movement.

    these listed disputes often resulted in casualties from all sides. riots, wars, imprisonment, and lynching are all commonly associated with racial conflict on severe levels.

      however, racism is an improving issue in recent decades. people are being more accepting and welcoming of diverse populations. though, the world isn't perfect and it will take much more time, if ever, until the world is rid of racism.

first of all, it's important to say that the book we shall not be moved, written by joan dash, is about the first strike of women in the united states in the year 1909. the best historical detail to clarify the reader's undertanding is the phrase "general strike". this strike involved women working at a garment factory who decided to protest   long working hours, low wages and brutal conditions. this strike became known as "the new york shirtwaist strike" or "the uprising of the 20,000". the strike mostly involved jewish women who did not speak english or who had a basic knowledge of the english language. finally, the strike went on from november 1909 until february 1910.
