Task 1 You are employed as a mechanical engineer within an unnamed research center, specializing in the development of innovative air conditioning systems. Your division is tasked with providing computer-based modeling and design solutions using computational fluid dynamics through ANSYS software. Your primary responsibilities involve the analysis of horizontal channel dynamics to meet specific criteria. Under the guidance of your immediate supervisor, you have been assigned unique responsibilities within an ongoing project. As a member of the research team, your role includes constructing an appropriate model and executing a sequence of simulation iterations to explore and enhance channel performance. Figure 1 provides a visualization of the horizontal channel under consideration. Consider 2D, incompressible, steady flow in a horizontal channel at a Reynolds number of 150. The schematic below illustrates the channel flow, not drawn to scale. For simplicity, neglect gravity. The…

Problem 1: You are working in a consulting company that does a lot of hand calculations for designs in Aerospace Industry for mechanical, thermal, and fluidic systems. You took the Virtual engineering course, and you want to convince your boss and the team you work to move to modelling and simulation in computers using a certain software (Ansys, Abaqus, etc). Discuss the benefits and pitfalls of computer based models used within an industrial environment to solve problems in engineering.

Problem 3: A small gearing system in your brand-new 3D printer fails as you were printing, leading to an overload in the motor and a fire in your home. The fire spreads, burning half of Everglades National Park in the worst environmental disaster in US history. The printer company blames you! Stating that you must have been misusing the printer some- how. Use your engineering knowledge to "show those jerks you mean business!" You investigate and find a serial number on the gears and type it into Google, finding the company that manufactures the gears. Their website provides some info that this series of gear is made from AISI 4340 steel and the yield strength is 125 kpsi. Assuming each gear tooth acts as a small cantilever, prove to the 3D printer company that they are liable for the fire. oct # Gear Information Gear radius (r): 1.00 in Tooth length (1): 0.15 in Tooth height (h): 0.15 in Tooth thickness (b): 0.1 in Angular velocity (w): 0.1 rad/s Motor Information Power (H): 0.009 hp 1…

Are you as strong as a horse? Purpose: To understand the concept of work and power and to calculate the power generated by yourself or a friend. Materials: A tape measure, stairs, and a stopwatch, cell phone, or wristwatch. Key Physics Concept: Power is the rate of doing work. Power can be calculated by dividing the work done by the time it takes to do the work; in this case we will do work against gravity on a stair case (you may add your power in doing pushups to test your arm power). Can you guess what your peak horsepower is? You may do the stairs one at at time or multiple stairs at a a time; whatever is most safe and efficient for you. Procedure: Observations: Analysis: Conclusions: Application: 1. Will your hp change if you performed the activity for a longer duration (for example, climbed the CN tower staircase)? In what way? Explain. 2. Research the horsepower generated by a car. How does the average person's peak power rating compare to it? How many average people would it…

2. (Inspired by a walk in Baker Student Center.) An escalator handles a steady load of 30 people per minute taking them from the first to the second floor through a vertical rise of 24 feet. Let us say the average person riding the elevator weighs 160 lb. a. What output power on a motor do you require to drive the unit? Take literally one minute to find an electric motor online that could do this job. You can search “_ hp electric motor" and state the motor name, power, cost, and vendor. Of course, round up your hp, not down to meet your specs. (In practice, this is an area where you can spec the motor in equivalent Watts, if you choose.) b. What is the electric power that is input to the motor considering losses within the escalator system due to friction, vibration, etc.? Your chosen motors surely have a different efficiencies and sources may even present efficiency as a function of power/rpm, so let's all use the value of e= 0.85 for consistency.

Problem 7 Marooned You are stranded on a boat with no way to paddle to the shore (and no water current to move the boat). You have mass 2m and the boat also has mass 2m. In addition, you brought 2 weights from the physics lab that each have mass m. Since you have been hitting the gym with Juan, you can throw the weights with an impressive speed of vo. (a) If you throw both weights off the back of the boat simultaneously, what will the speed of the boat (and you) be? (b) Suppose instead you throw each weight off the back of the boat individually. What will the speed of the boat be in this case? (Be careful when considering how fast the second weight is thrown with respect to the water). (c) If you were trying to get to shore as fast as possible, which method should you choose? Should you throw the weights towards shore or away from shore?

PART D

You have been asked by your supervisors at A&L Engineering to design a roller coaster for a new theme park. Because this design is in the initial stages, you have been asked to create a track for the ride. Your coaster should have at least two peaks and two valleys, and launch from an initial height of 75 meters. Each peak and valley should represent a vertical change of at least 20 meters. In your design, you should plan for a mass between 400 and 600 kilograms. Once you have designed the track, you have been asked to calculate the kinetic energy, potential energy, momentum, and work done by the cart at various points throughout the track. Unless otherwise stated, you can ignore the effects of friction. Following your calculations, you have been asked to describe the energy transfers detailed by these equations. Directions To complete this roller coaster design report, complete the following: Create a diagram of a roller coaster track containing at least two peaks and two…
