The figure below shows a section of hot-water pipe consisting of three parts: a straight, horizontal piece h = 28.0 cm long, a straight vertical piece ℓ = 110 cm long, and an elbow joint that allows the two pipe sections to meet at a right angle. An illustration shows the inside of a wall where an L-shaped water pipe goes through it. The vertical part from the top of the wall to the elbow is labeled ℓ. The horizontal part from the elbow to the beam in the wall is labeled h. A stud and a second-story floorboard hold the ends of this section of pipe stationary. The pipe is made of a copper alloy with a coefficient of linear expansion of 1.7 ✕ 10−5(°C−1). When the water flow is turned on, the temperature of the pipe rises from 18.0°C to 42.5°C. What is the magnitude and direction of the displacement of the pipe elbow from its original location once the pipe reaches the higher temperature? (Give the magnitude in mm and the direction in degrees below the +x-axis, which is parallel to the horizontal piece, and points from the stud to the elbow joint.) magnitude mmdirection °
