Questions parabolic reflectors only. This statement is: (1) All satellites use correct or incorrect. [2] The principal axis is drawn: outward from the center of the surface, so that surface is symmetrical about the axis, so that all-reflection occur along the entire axis, outward from end of the surface. [3] The parabolic reflector focuses on: a parabolic shape, a spherical shape, a single point a small line. [4] The spherical reflector...

1) A bridge is built in the shape of a parabolic arch. The bridge arch has a span of 180 feet and a maximum height of 30 feet. Find the height of the arch at 20 feet from its center. 2) A searchlight is shaped like a paraboloid of revolution. If the light source is located 3 feet from the base along the axis of symmetry and the opening is 8 feet across, how deep should the searchlight be?

4. Parabolic/cylindrical trough: (Total points 45) Suppose you are planning to make a cylindrical trough from metal sheet of size 5m X 7m. The metal sheet is aluminum coated, having 95% reflectance. You gave this sheet a semicircle shape along its width so that the arc length of semicircle becomes 5 m. If a collector pipe made of copper, with the length 7m and diameter 5cm (inner diameter 3cm) is at the focal point of this trough, receiving concentrated light,...

15. Assume that the surface of a part has a profile given by y = 1.5x10^-6 in sin(2x/in). Both x and y are in inches. Answer the following questions: a. What is the distance between peaks? b. What is the value of Ra AA over 1 inch length? c. What is the value of Ra RMS over 1 inch length? d. What process may have produced such surface? Use a chart from the internet or elsewhere to support your answer.
