One of the starting materials Piperonaldehyde has an easily identified peak on the HNMR spectra and the IR spectrum. Draw the structure of this starting material and circle the proton for the HNMR that has this easily identified peak. Also, circle the nctional group on the structure that is responsible for the peak on the IR. detect any of this starting material in your product's HNMR and IR? (4pts) fu Did you

6. Material deformation and exponential behaviors Creep is a thermally activated process by which materials undergo slow, permanent, deformation. It is described by the following equation: = Ce-oc/RT, also written as. E = exp(-RT) where έ is the creep rate, C is a pre-exponential constant determined experimentally, Q. is the activation or threshold energy required for the process to occur, R is the universal gas constant, an T is absolute temperature. To experimentally determine Cand Q. for a particular material,...

Material enginering You required to select suitable alternative materials used to produce present day cars. You must do this realising that energy is used to build cars and run them. Consumers and legislation want more fuel-efficient cars. You should suggest materials for the car based on its ability to have the necessary stiffness, strength, formability, and weldability. In addition you must also consider manufacturability, maintainability and disposability at the end of life; i.e., to be disposed of, or recycled, in...

Selection of materials One of the most challenging task of materials engineer is the proper selection of the material for a particular job, e.g., a particular component of a machine or structure. An engineer must be in a position to choose the optimum combination of properties in a material at the lowest possible cost without compromising the quality. A number of questions need to be answered before a decision can be made as to the specification required of a material...

A small accounting firm recently leased a new document management device (an all-in-one machine capable of printing, scanning, copying, and faxing) for three years. Reliability was a deciding factor. The company’s research found that during any given year, approximately 86% of the devices sold in one particular model required no service in a year, 9% needed one repair, 4% needed two repairs, 1% required three repairs, and none required more than three repairs in a year. Considering this information to...

Bubble Company produces a variety of bottles from recycled plastic. The company has one particular machine on which it can produce either of two types of water bottles, 1-liter bottles or 1/2-liter bottles. Sales demand for both products is such that the machine could operate at full capacity on either of the products, and Bubble can sell all output at current prices. One unit of the 1/2-liter product requires one hour of machine time per unit of output, and one...
