Apply geometric tolerancing to part according to the instructions below. This exercise will provide you with experience in correctly applying and interpreting geometric tolerancing symbology. If you have trouble applying the symbols, page through this unit looking for similar examples. The Hole Bar in this unit is a good reference. Draw symbols and feature control frames clearly and neatly. 1. Establish the right face in the side view as datum feature A. Qualify this feature with a flatness of .005. 2. Establish the top surface in the front view as datum feature B. Qualify this feature with a perpendicularity of .005 to datum feature A. 3. Establish the left surface in the front view as datum feature C. Qualify this feature with a perpendicularity of .005 to datum features A and B. 4. Establish all necessary dimensions as basic. 5. Position the .250 hole within a diameter of .005 RFS relative to datum features A,B,C. 6. Position the three holes within a diamter of .012 at MMC relative…
You have a telescope that consists of two converging lenses which are placed a distance apart which is approximately equal to the sum of their focal lengths. Focal length 1 is appriximatly 5.5cm and focal length 2 is approximatly 25cm. The lens closest to the onject should have a resonably long focal length and the eyepiece lens should have a relatively short focal length to get good magnification. a. draw a scale ray diagram for a telescope using one long and one short focal length lens. b. Estimate how much larger your distance object appears through your telescope and then calculate the angular magnification.
Problem 5 Please draw the top view of the object, whose front view and right side view are shown as following:

These images show one of the large `VLT’ telescopes at the European Southern Observatory’s facility at Cerro Paranal, Chile. The place where the laser beam comes out (seen in the inset photo) is just out of sight off of the top edge of the large photo. Also note that if you look down the telescope tube (in the main photo), you can see the tube’s front-end structure. Why is there a laser beam shooting out of the front of this telescope (in the inset picture)? Group of answer choices The beam creates an `artificial star’, which is used by an adaptive-optics system to measure (and counteract) the blurring effect of Earth’s atmosphere. The astronomers are bouncing light off of objects near the center of the Milky Way galaxy, to measure their distances from Earth. The astronomers are taking pictures of the surface of a planet (most likely Mars), and the laser allows them to light up the planet’s surface with a very specific color of light. The astronomers are engaged in the opening…
