    Chapter 2: Mechanical Design 8 Problem P2.7: Give three examples of engineered products that have a specific minimum weight, but no specified maximum weight and specify the approximate minimum weight. Examples include: ⋅ Helium balloon holder (minimum weight will depend upon how many helium balloons are being held) ⋅ non-wedge based door stop (minimum weight based on friction coefficient) ⋅ racecar (minimum weight based on racing regulations) ⋅ competition bike (minimum weight based on racing regulations)

    Chapter 2: Mechanical Design 9 Problem P2.8: Give three examples of engineered products that have to be precisely a certain weight, and provide the weight. Examples include: ⋅ balancing weight for car wheel ⋅ coins (weight used to count coins in some automated machines) ⋅ precious metal coins (weight dictates worth) ⋅ exercise weights (15 lb weight must be 15 lb)

    Chapter 2: Mechanical Design 10 Problem P2.9: Give three examples of engineered products that fulfill their designed purpose by failing or breaking. Examples include: ⋅ saw stop mechanism (http://www.sawstop.com/) ⋅ crumple zone in car ⋅ bumper (foam insert) in car ⋅ bike helmet ⋅ frangible bullets (split up when they hit anything other than flesh) to protect bystanders ⋅ stress indicating paint has fluorescent dyes capsules that split under known deflections (http://www.newscientist.com/blog/invention/2007/10/stress-sensitive-paint.html) ⋅ Some meds are packaged in glass bottles that you break to open ⋅ Cover on a “pit trap” breaks when weight is applied ⋅ Fire suppression sprinkler detection device (solder connect melts or glass connection shatters)

    Chapter 2: Mechanical Design 13 Problem P2.27: For the magnesium camera body shown, provide an explanation for which processes you think were used in its manufacture and why. This was most likely manufactured using a die cast procedure because of the material and geometric detail in the pieces including a number of inclusions. Certain features could have been machined, and some polishing/grinding operations may have been used.
