(15 pts) A certain polymer needs to be heated by a heat lamp for at least 1 minute to cure properly at 50° C. The optimum height of the heat lamp above the parts is 75 cm. The heat lamp can maintain the temperature at 50° C within a circular cone with an angle of 25° looking straight down. a. Provide a sketch that would help you solve this problem: i. If the conveyor belt is moving at 5 m/min (meters per minute) how many heat lamps must be placed in succession above the parts to cure them properly? Parts fit within the area heated by the lamp. ii. Explain briefly what is on your sketch and your thinking in drawing it. One paragraph of text will suffice. Label items on your sketch and indicate known values. List any assumptions you are making. b. Extra credit (10 pts): Calculate the solution to this problem, i.e. find out how many lamps will be required.
