Example Questions for Quiz 1 MSE 102: Applied science, technology and Society Notes: 1)
These are a set of practice questions for the MSE 102: Applied Science, technology and society Quiz. 2)
Not all questions have the same number of assigned marks. The relative weight of questions will be provided in the Quiz. 3)
You may take a single sheet of paper (writing may be on both sides), containing your notes, into the Quiz. You have been asked to develop a fire safety system for the new SRYE building. Provide a list of specifications and their associated metrics. Aim to provide at least 5 specifications and associated metrics. Guess any unknown values. A car is traveling at 45 mph. Convert this to m/s. Note that 1 mile = 1609 m. You have a potentiometer that has a high bias and high precision. Explain how taking repeated readings will likely compare against the actual value. What is the power dissipated across a resistor with a resistance of 20 kΩ ± 5% and a current of 150 mA ± 10 mA. Give the expected error range. You have been given an equation to determine how air moves due to atmospheric affects, with an unknown term, x
. Determine what the SI base units are for this unknown term. 𝑓 =
𝑚
𝜌
𝑥
where 𝑓
is force, 𝑚
is mass of air and 𝜌
is the density of air (mass per unit volume). Region A can export a significant proportion of the electrical energy is generates to Region B. Region A can also import a significant amount of the electricity it needs from Region B. What
properties of the electricity grids and the electrical energy generation mixes of Region A and B allow for these large transfers of electricity? You are required to design the electrical energy mix for a large remote island. You intend to have an installed capacity of 20 MW; the maximum predicted load is 14 MW and the minimum is 6 MW. You are required to have 60% of your installed capacity made up of low carbon energy sources. The terrain on the island will only allow for one hydroelectric dam, with a maximum energy production of 5 MW. Choose the energy mix for your island. Assume all required natural resources are available. State any additional assumptions you make. You must have at least 3 different types of energy sources and no more than 5. State what your energy sources are and why you choose them. You are measuring how long your friend can make a coin spin until it falls over. What are the sources of systematic and random error? With regard to measurements, what is a slug? What are the base units for pressure, using the SI system? Recall that F=ma, P = Force/Area. You are working with a stop watch that has 2% accuracy and a speedometer that has an accuracy of ± 2 mph. You are travelling at constant speed of 25 mph. How far will you travel in 30 minutes (measured using your stop watch) and what are the error bounds on this value? Provide 2 distinct difficulties with having an electricity grid that is 60% wind energy and 40% nuclear energy. Give two other examples of Canadian’s using energy besides electricity.
You have been asked to design a sensor to determine if a person is sitting, standing or walking. Give 3 specifications for your sensor with associated metrics. You are working on designing a new method to identify different types of polymers from domestic recycling. You have been tasked with looking for external ideas for this project. Name four different types of external sources of information that would be appropriate for this project. You have been asked to design a device that an elderly person can use to assist them in collecting apples from an apple tree. Provide a list of specifications that included a metric (with numerical value where possible). Your team are to design a new concept for a guard rail. Specifications: Safe (high priority) Aesthetically pleasing (medium priority) Does not inhibit view (low priority) Provide metrics that are based on these specifications.
