During coastdown testing of a family passenger car, the following road load drag force characteristic was derived: FRL = 0.392v²+162 Where FRL is given in Newtons, and v, the vehicle speed in m/s. It is desired that the vehicle should have a top speed of 200km/h. Assuming a transmission efficiency of 90%, which of the following engines would be most suitable? Type BMEP (Bar) Maximum Engine Cubic Capacity Speed (rpm) (CC) Normally aspirated SI engine 11 6500 1400 Turbocharged Sl engine 16 6000 950 Normally aspirated Cl engine 8.5 4500 2400 Turbocharged and aftercooled CI 12 4500 1800 engine

True or False High-tech research in Singapore includes the elusive but all-consuming invention that drove Nicola Tesla - Wireless Power Transfer.

Linda and Jerry are faced with a car replacement opportunity where an interest rate can be ignored. Jerry’s old clunker that averages 10 miles per gallon (mpg) of gasoline can be traded in toward a vehicle that gets 15 mpg. Or, as an alternative, Linda’s 25 mpg car can be traded in toward a new hybrid vehicle that averages 50 mpg. If they drive both cars 12,000 miles per year and their goal is to minimize annual gas consumption, which car should be replaced—Jerry’s or Linda’s? They can only afford to upgrade one car at this time.

In the emission testing of motorized vehicles, the instrument used for gas engines is different from the instrument used for diesel engines. Why? What are the differences between the two instruments? Explain your answer within the context of the concepts and principles of fuels and combustion.

I asked bartleby to solve this question earlier, it gave me AI answer which is completely different to what's shown in this answer. I don't know which one is correct now. I have attached screenshots of the AI answer. Can you clarify which is correct. Also I previously asked about pv diagram and you said ' the curve in the explanation is correct', did you mean in your explanation or the one I showed as an example? Please advice

C Dynamic Analysis and Aeroelasticity SECTION B Answer TWO questions from this section ENG2012-N The moment of inertia of a helicopter's rotor is 320kg. m². The rotor starts from rest and at t = 0, the pilot begins by advancing the throttle so that the torque exerted on the rotor by the engine (in N.m) is modelled by as a function of time (in seconds) by T = 250t. a) How long does it take the rotor to turn ten revolutions? b) What is the rotor's angular velocity (in RPM) when it has turned ten revolutions?

The activities, duration and cost under normal and crashed conditions for a network diagram are shown in the accompanying table.    1. Determine the normal duration of the project 2. Determine the normal cost of the project 3. Determine the critical path under normal conditions.

C O O n t e n t Explore some of the projects described by William McDonough (Liuzhou City, Ford River Rouge Truck Plant green roof, Gap San Bruno office, etc). • What became of them? Consider the gap between ambition and reality when it comes to sustainability and sustainable energy generation. Discuss how this gap relates to the perspectives given in the other TED talks as ● well. Do you agree with the presenters' perspectives on the future? • What sustainability factors are they considering (or not) in their assessment of the future?

I want to briefly summarize what he is talking about and what you conclude. pls very urgent
