Beam ac is supported by two vertical solid rods ab and cdthat have diameters of 12 mm and 8 mm, respectively. determine the position d of the 6 kn load if the normal stresses in the two rods are the same. also calculate the corresponding normal stress in each rod.

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
