Tres barras hechas de materiales diferentes están acopladas y colocadas entre dos paredes a una temperatura T1 = 12 ºC. Determinar la fuerza ejercida sobre los apoyos (rígidos) cuando la temperatura alcanza T2 = 18 ºC. Las propiedades de los materiales son Yacero = 200000 N/mm2, αacero = 12 x10-6 ºC-1, Ylatón = 100000 N/mm2, αlatón = 21 x10-6 ºC-1, Ycobre = 120000 N/mm2, αcobre = 17 x10-6 ºC-1.

Someone answer asap for ! the boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a. e = 2b - 212 b. b = 2e - 212 c. e = -2b + 212 d. b = -2e + 212

Someone me! will award brainliest if u explain and answer!
