IDerive the value of thermal resistance in aCylindrical wall
The theoretical failure strength is significantly higher than the empirical failure strength of polycrystalline materials, even when they are highly polished because: a) Polycrystalline materials have little or no capacity for plastic deformation, so they have lower failure stresses b) Plastic deformation in polycrystalline materials adsorbs energy which reduces their failure strength c)The energy needed to break the atomic bonds in crystal lattices is lower in polycrystalline materials as compared to in single crystals d)Polycrystalline materials contain internal discontinuities
As a technologist, you are given the following design task: In a manufacturing environment, the final product needs to be packaged and sealed. After the product is placed inside the plastic bag, a hot pressing die is to be used to seal the plastic bag by application of heat and pressure. The operation should be as follow: By pressing a pushbutton switch, the heating rail is advanced and the packaging material is heated along the adhesive strip. After the adhesion pressure has been reached, the heating rail must return to its start position The design specification includes the following: Pressure dependent reversal with monitoring of the end position by means of magnetic proximity switches. Include safety measures, a green light to show when the system is ready, a red light when system is in operation, a warning sound when the heating rail is moving. 1. Draw your pneumatic circuit design for this application. 2. Draw the electric circuit diagram for your design.

A package of frozen fish sticks have different instructions when they are heated up on the stove as compared to using the oven. Stove: Heat over medium flame for 2 minutes. Then flip the fish sticks (turn them over) and heat them for another two minutes. Oven: Preheat the oven to 375 F. Put them on a metal baking sheet for 15 minutes. a. Explain why the instructions have you flip the fish sticks over when you’re heating them with the stove, but not with the oven. b. If you follow the oven instructions, the side of the fish sticks touching the metal baking sheet will cook more than the top side of the fish sticks. Explain why.
