MATLAB based problem: Create a motoring model for the engine with the following specifications, and plot the in-cylinder pressure against (i) cylinder volume and (ii) crank angle degrees (20 points)  Bore = 107mm, stroke = 124mm, compression ratio = 17.3, Length of connecting rod = 192mm. Assume the ratio of specific heats is 1.4 (constant), atmospheric pressure is 1 bar and ambient temperature is 298 K.

You are to present a research proposal with regards to the topic of "Investigation of the Mechanical Properties of Atherosclerotic Plaque Tissue", however for this to be successful, a "good" research question(s) must be made. Give examples of "good" research question(s) to motivate the said topic and go further from here. The idea need not to be original but should be researchable and presentable to fellow academics. The Internet is there at your disposal. It is important to take into consideration that this research question(s) can define the topic, define the research nature of the research endeavour (i.e. to explain, to discover, to describe, to compare etc.), define the questions of interest (i.e. who, what, when, why or how etc.), define the constructs and variables and what their effects are.

Consider a small Pelton wheel hydro turbine, with a total head (reservoir surface to nozzle elevation difference) of Ht = 200 ft. The flowrate to the turbine is 185 gal/s. If the pipe (penstock) feeding the turbine has a length of 1000 ft, a diameter of 19.6 in, and a friction factor of f = 0.005, determine the percent of total head lost in the pipe (penstock). Submit your answer as a percentage but without the percent symbol. ***NOTE: The value of the friction factor f is consistent with the definition in our textbook (and may differ from other textbooks). Using our textbook's notation, you could also use f' = 4f = 0.02.***

Using words and visuals, briefly describe the temperature dependence of stiffness for the following classes of polymers. Explain how the structure and bonding in these materials contributes to the observed temperature-dependent properties (structure-property connections).

Amorphous and semi-crystalline thermoplastics

Elastomers

Thermosets

Architectural plans question: when reading the specifications of construction plans; the specification calls for anchor bolts that meet ASTM standard F1554 Grade 36, do these standards give the size of anchor bolts needed? In general what type of information does ASTM standardize ? (material and sizing?)

An oil at 50C with properties similar to engine oil passes through a 30 cm diameter pipe with an average velocity of 6 m/s. A 200 m long section of pipe passes under a frozen lake with waters at 0 C. The pipe has the same surface temperature as the lake water.

(a) Find the temperature of the oil as it leaves the lake. Neglect the thermal resistance of the pipematerial.

(b) At what rate is heat transferred from the oil?

Lets say I have a second order ODE: mx''+kx+bx'=kz+bz' ( an EOM where m=3000, b=2000, k=50000, and finally z=.01sin(3.5t)).

In Matlab, how would I use the Matlab command ode23 to solve this ode assuming zero initial conditions, range :0-20 seconds.

P5. Coal power plants operate at high temperature of about 600C, whereas a jet engine operates at high temperature of about 1200C. Would you recommend replacing the coal power plant with the jet engine for power production? Justify your answer.

Consider a Kantrowitz-Donaldson diffuser designed for a flight Mach number of 1.8. The entrance area equals 3.0 ft2and the ambient airtemperature and pressure are 500R and 0.8atmosphere. The flow is isentropic everywhere except across the normal shockwave. Determine:(a) the minimum cross-sectional area of the throat such that a normal shock may be stabilized at the entrance, (b) the maximum mass flow, and(c) the maximum stagnation pressure possible at the end of the diffuser (with subsonic flow only in the divergent portion).In each of these optimizations, consider the flight Mach number fixed at the design value while the final pressure (at the end of the diffuser) is allowed to adjust.

A Carnot heat pump moves heat to a warm house at 24°C at a rate of 300kW. The heat is pumped from the outside air at 7°C. What is the power required by the heat pump?

What is the rate of change of entropy for each of the thermal reservoirs (the house, and the outside air)?

Does this heat pump satisfy the second law of thermodynamics increase of entropy principle?

a. A shaft is used to transmit power. What does this mean?

b. Explain the general process of choosing a material for a shaft.

c. Discuss the considerations that must be made when selecting the layout of a shaft.

5. A fluctuating external load of Ppeak = 4500 lb is applied at the bolted joint given in Problem 4.
(1) Find the factor n_f of safety against the fatigue failure using the modified Goodman criterion.
(2) Find the factor n_p of safety using the proof strength line.
(3) Find the factor n₀ of safety against joint separation.
