Chapter 3: 13. What type of geometric tolerance has no datum features? 14. A theoretically exact dimension is called a 15. The feature symbol specifies that a group of two or more interrupted features of size are to be considered one single feature of size. 16. For an individual regular feature of size, no element of the feature shall extend beyond the maximum material condition boundary (envelope) of perfect form. This statement is the essence of 17. What is the name of the symbol used to identify physical features of a part as a datum feature and must not be applied to centerlines, center planes, or axes? 18. The is the condition in which a feature of size contains the maximum amount of material within the stated limits of size. 19. The total positional tolerance equals the sum of the tolerance and the tolerance.

Subject name: Theory and design for Mechanical measurements

A datum when used in manufacturing is primarily used for?     Define the functional relationship to another feature on a part, or they have a functional relationship in an assembly. They are the origin from which many Geometric tolerances are measured.     Datums are used to describe how one part must fit or align to a mating part.     A datum should be placed on the smallest surface of the part to be sure that the mating part would fit.     Datums assure that parts will always fit together.

7. Why are land and groove markings on a bullet considered Class Evidence, while the striation markings on a bullet are consider Individual Evidence? 8. You recover two bullets from the wall of a crime scene. These recovered bullets are visible below: Bullet #1 Enlarged View Enlarged View Bullet #2 Actual Size Actual Size Bottom View Bottom View Bottom View Bottom View Complete the Evidence Table below. You can easily convert millimeters to inches (if needed) using the following formula: # of millimeters # of inches 25.4 mm per inch Firearm likely produced by what manufacturer? Approximate Bullet Evidence Table Direction of # of Lands Caliber Twist (English) Bullet #1 Bullet #2 Do you believe that Bullet #1 and Bullet #2 were fired from the same gun? 86

Given the following sentence descriptions of the geometric tolerance information, correctly sketch the feature control frames for each and include in your lab report. i. The planar surface must be parallel within a thousandth of an inch tolerance zone relative to datum feature A. ii. The axis of a cylinder must be perpendicular within one- hundredth of a millimeter cylindrical tolerance zone at maximum material condition relative to datum feature D. iii. The total runout of the surface must be within a five- hundredths of a millimeter tolerance zone relative to datum feature A. 13 iv. The total surface profile of the surface must be within a two-thousandths of an inch tolerance zone relative to datum feature A. v. The axis of a hole must be positioned within a five- thousandths of a millimeter cylindrical tolerance zone at maximum material condition relative to primary datum feature D, secondary datum feature E, and tertiary datum feature F.

I need answers with clear hand writing or using Microsoft word . ASAP   measurements , describe how to read the values given on the measurement tools and to write about measurement tools note: i want a lot of information

why in general you might want to use an indirect method to measure something more accurately.  Give 1 example of something that we measure indirectly vs. directly and why

Please answer questions 12 and 13 thanks
