Theory and Design for Mechanical Measurements

Measurement is a term that refers to analyzing a manufactured component regarding the degree of accuracy for dimensions, tolerances, geometric profile, roundness, flatness, smoothness, etc. Measurement always involves comparing the manufactured component or the prototype with a standard specimen whose dimensions and other parameters are assumed to be perfect and do not undergo changes with respect to time.Precisely in mechanical engineering the branch that deals with the application of scientific principles for measurements is known as metrology. The domain of metrology in general deals with various measurements like mechanical, chemical, thermodynamic, physical, and biological measurements. In mechanical engineering, the measurements are limited to mechanical specific such as length, mass, surface profile, flatness, roundness, viscosity, heat transfer, etc.

Basic principles of engineering metrology

Metrology is described as the science of measurement, precision, and accuracy. In other words, it is a method of measurement based on units and predefined standards.

Statics and Principles of Moments A seesaw that weights 45lbs and its 5m long is balanced on the fulcrum in the center. 1- Two children are sitting on opposite sides of each other on the seesaw. One child weights 50lbs and is sitting 0.7m on the left side. Where should the other child sit in order to be balanced on the seesaw if they weigh 42lbs? 2- Now, another child wants to sit on the seesaw and weighs 30lbs and is sitting 1.25m in front of them and is closer to the fulcrum. What are the CW and CCW moment of the seesaw now? What is the net moment and direction? 3- Then, a fourth child wants to play on the seesaw and is on the left side of the plank in order to bring the system to equilibrium. How much does the child weigh (Calculate the pounds of force needed in order for rebalance?) 4- Now the fourth child leaves the other three children sitting on the plank.

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.
