The Ford Expedition has a 65.5-in. track and a 20-ft turning radius. The P265170R17 tires have a nominal radius of 15 in. If the vehicle was designed with a solid rear axle (i.e., no differential), calculate the amount of wind-up in the rear axle when the vehicle performs a 180" turn at minimum radius. (Answer: 2.18 revolutions.) (with explanation and details please)

The TED talk by Katherine Kuchenbecker was extremely controversial and brought about different aspects of robots and AI that I had previously never thought of. Throughout her video, she focuses on Haptics, which refers to touch technology. As we are aware, this is one of the things that differentiates us from robots, thus the controversial debate begins. Should we give robots the power to feel and touch, just like humans do? I believe that there are both positive and negative outcomes that can erupt from doing such a thing. On the one hand it can be beneficial in some medical fields such as dentistry in which people would become more experienced and knowledgeable before they actually begin their job as a dentist as they would be able to detect cavities based on their feel through this innovative technology. Another example that I enjoyed learning about and thought that was great was when it comes to exhibit museums. There are many instances in which we are not allowed to touch a work of art or sculpture and it is very hard to imagine how if would make us feel. If this were to be achieved through this new technology without actually having to touch the sculpture itself, it could really change and challenge the way we see and experience art. However, although there might be some positive aspects to this technology, there are also disadvantages that come with it. I really believe that feel and touch are senses that differentiate us from robots and it is a difference that makes us special and unique. I think that giving up this privilege could bring about negative consequences within society and provide people with fake and false confidence. I think that if this technology develops, we have to be careful with the way we manage it and we should consider not completely giving up all of the things that make us unique and special such as the fact that we can touch and feel.

An unbalanced engine mounted on an elastic support imposes a periodic vertical force on the support at the rotational frequency of the engine. In order to determine the relationship between the engine rotational frequency and the resonance frequency of the elastically supported engine, the engine run speed was slowly increased from its normal value of 550 rpm to 825 rpm, which resulted in a trebling of the amplitude of the measured displacement. No resonance was observed in the displacement response in the range of speeds investigated. Assuming that the damping present in the existing elastic support is negligible, determine: The natural frequency of the elastically supported engine is ----- rad/s?

The displacement volume of an internal combustion engine is 2.21 liters. The processes within each cylinder of the engine are modeled as an air-standard Diesel cycle with a cutoff ratio of 2.5. The state of the air at the beginning of compression is fixed by p1 = 1.6 bar, T1 = 325 K and V1 = 2.36 liters. If the cycle is executed 2100 times per min, determine: a) the compression ratio, b) the net work per cycle, in kJ, c) the maximum temperature, in K, d) the power developed by the engine, in kW, e) and the thermal efficiency.

An air-standard dual cycle has a compression ratio of 9.1 and displacement of Vd = 2.2 L. At the beginning of compression, p1 = 95 kPa, and T1 = 290 K. The heat addition is 4.25 kJ, with one quarter added at constant volume and the rest added at constant pressure. Determine: a) each of the unknown temperatures at the various states, in K. b) the net work of the cycle, in kJ. c) the power developed at 3000 cycles per minute, in kW. d) the thermal efficiency. e) the mean effective pressure, in kPa.

An air conditioner using refrigerant-134a as the working fluid and operating on the ideal vapor-compression refrigeration cycle is to maintain a space at 30°C while operating its condenser at 1000 kPa. Determine the COP of the system when a temperature difference of 2°C is allowed for the transfer of heat in the evaporator. (Take the required values from saturated refrigerant-134a tables.)

The COP of the system is ?

Is there an observable trend or difference between all the flowmeters readings (venturi, rotameter, and orifice) and the system flow rate (obtained using magnetic or coriolis flowmeters?

Give a scientific method or ways to determine, investigate, or analyze the characteristic and behaviour of electric-powered two and three wheelers in terms of the factors such as safety, travel time, accessibility, cost for a user. I need help for a research class on determining the characteristic and behaviour of people.

What is Freezing Range? Describe the significances of Freezing Range of a material in casting.

Air enters the diffuser of a ramjet engine at 22 kPa, 228 K and a velocity of 920 m/s, decelerating to a negligible velocity at the point at which heat is added. Using cold airstandard analysis with constant specific heats at 300K, determine the following if the exit pressure is 22 kPa and heat is added at 750 kJ per kg of air:
(a) The pressure at the diffuser exit, in kPa.

(b) The velocity at the nozzle exit, in m/s.

(c) If the fuel used requires a temperature of 900K to auto-ignite, is the craft moving fast enough to use this fuel? If not, what minimum speed must it be moving such that the air temperature after compression will ignite the fuel?

Five kg of oxygen (O​2​), initially at 430°C, fills a closed, rigid tank. Heat transfer from the oxygen occurs at the rate 425 W for 10 minutes. Assuming the ideal gas model with ​k
​ = 1.350 for the oxygen, determine its final temperature, in °C.

Can't seem to find the right equations to use for this one, so I'm getting pretty stumped. Any help would be greatly appreciated

In this exercise we will utilize the tables for superheated water vapor, (D-3). All graphs should be generated using plotting software, e.g. Excel, MatLab, etc. (If you use NIST, do NOT utilize the built-in plotting software to generate your graphs.) Plot the specific internal energy and the specific enthalpy Vs T(K) at 1 bar. (Use a reasonable number of available temperature values but include the maximum and minimum values.) The lower limit of the ordinate should be 2500kJ/kg and the lower limit of the abscissa should be 300K. Observe the nature of the relationships and based on these calculate the ratio of specific heats, gamma. Plot the compressibility factor as a function of temperature for 1 bar and 120 bar and comment on the significance of intermolecular forces. The compressibility factor of a gas is 0.94152 when the temperature, pressure and specific volume are -50 degree F, 30atm and 0.018317m^3/kg, respectively. Which gas is it?
