Homework Answers
Product designed by Mechanical Engineers
Product designed by mechanical engineers is Internal combustion engine(IC Engine), Power plant equipment such as turbine, heat exchanger and power-consuming devices such as Air-Conditioner, Refrigerator.
Products designed by Civil Engineers
Infrastructure products designed by civil engineers are such as Road, Airport, Flyover, Railway projects, dams and bridges. They supervise these ongoing infrastructure activities.
Yes, material properties change with temperature, pressure humidity other environmental factors. Every component used in machines or construction project has its own life. There is life upto which it can operate safely after that we need to replace or repair that certain component. Material properties change with time and its cause of concern for both mechanical and civil engineers those who look after machines and construction projects.

6. The median, or Q2, is nothing special. When creating a sign test, we could have designed the testing infrastructure around the first quartile, Q1, instead. Suppose we set a null hypothesis of Ho: q = go, where q is a symbol for the first quartile, go is a constant, and we are dealing with a continuous random variable X. a. Assuming Ho, we collect n values from X: Xi,..., Xn If U is the number of observations less than...

Read the case study below and answer the questions accordingly. An elevator manufacturing company Miss Frans, the general Manager of a company manufacturing elevators, was frustrated with the lack of co operation between the mechanical engineers, who designed new elevators, and the manufacturing engineers, who determined how to make the elevators. The mechanical engineers would often design an elevator without consulting the manufacturing engineers and expect the factory to figure out how to build it. The products were difficult or...

Product Design Assignment: this week we examine product and service strategies. One issue with products/services is they many fail to update to current technology or consumer needs. This week we are going to examine how an outdated/bad product was initially developed and what need it served. Then define how the current needs/technologies have changed with respect to the product/service. Finally, redesign the product/service to the current needs/technology. The steps for the assignment are: 1. Recreate the requirements gathering process that...

Consider a two-mass-spring flexible mechanical system given below. Mass 1 Mass 2 In the system, u(t) is the input force, k = 1 is the spring constant, #1 and x2 are, respectively, the displacements of Mass 1 and Mass 2, which have masses of mı = m2 = 1. Assume that there is no friction on the surfaces. (a) Drive a differential equation of the mechanical...

Large and heavy products require a range of material handling systems to move the products through the various stages of production. This normally incorporates large lifting equipment, conveyor systems and specialised transfer devices to move the products from one handling system to another One such device commonly found in paper-mills is the V-link transfer station, designed to move large, heavy rolls of paper from a conveyor system to a fork lift truck. A few examples are shown below. DESIGN BRIEF:-...

Power Train, Ltd. We have smashing systems for reporting, tracking, and controlling costs on design projects. Our planning of projects is better than any I have seen at other companies. Our scheduling seemed to serve us well when we were small and we had only a few projects. Now that we have many more projects and schedule using multiproject software, there are too many occasions when the right people are not assigned to the projects deemed important to our success....
