Maneuvering Performance and Operational Limitations

Intro to Transport Processes TRUE or FALSE. Please provide a quick explanation thanks! 1. Each molecule of a system has a certain quantity of mass, thermal energy, or momentum associated with it. 2. Momentum transport in a fluid depends bulk movement of molecules and not on individual molecule of the system.  3. At same mass, the momentum of a molecule is greater than the other molecules if it has less velocity?

We learned that engine design can alter / change engine performance, that by increasing the engine displacement, engine power can be increased. Experts commonly agree that there are three (3) ways to increase the displacement of an engine. Question: 1)Explain the 3 ways of increasing the engine displacement? 2) Explain the commonly used alteration method used by car racers.

Please Answer the following question step-wise with detailed explanations. Thanks in advance?❤️

Question 45 is based on the following picture. Reprinted with permission from Popular Science magazine, ©2000, Times Mirror Magazines, Inc. 45. Stuart Wilkinson, the engineer of "Chew- Chew" said, "we stole the idea of eating food from the biological world, but we are marrying that idea to useful robotic capabilities." Which of the following would not be an application of Stuart Wilkinson's theory? A. A leaf mulcher that feeds on foliage B. a trash compactor that feeds on garbage dos C. a lawn mower that feeds on grass bos 9D. a garden cultivator that feeds on soil clippings E. a recycling truck that feeds on petroleum conjo

C)If both cyclists have 170 mm cranks on their bikes, what will be the mechanical advantage (considering only the movement of the feet with a constant force for walking and riding), in percent, that each rider will have achieved over walking the same distance? (This can be found by dividing the distance wallked by the distance the feet move in riding.)

2. For each of the situations described below, use an initial value problem to model the situation. Clearly define any variables and functions used. Do not solve the initial value problems. a. A 60kg ball is released from rest 3km above the Earth. Its drag force has a proportionality constant of 50 . Model its velocity as a function of time. m b. Air conditioning is turned off in an empty building. Initially, at 6PM, it has an interior temperature of 60°F. The building has a time constant of 4 hours. (Note: This is the time constant, not the constant of proportionality in Newton's Law.) The outdoor temperature fluctuates sinusoidally, reaching a maxmimum of 100°F at noon and a minimum of 60°F at midnight every day. Assume there are no heating or cooling effects on the build aside from Newton's Law of Cooling. Model the building's temperature as a function of time.

Most collisions are inelastic, meaning the kinetic energy is not conserved in the system.  (a) What are the three most common ways for energy to leave a system during a collision?  To the best of my knowledge, the use of the word "perfectly" in a perfectly elastic collision is not necessary.  Any elastic collision is a perfectly elastic collision.  Both concepts mean the kinetic energy is conserved.  The use of the word "perfectly" in perfectly inelastic collisions is just telling you that the two objects end up sticking to each other (have the same final velocity).  (b) Combine the equations for the 1-D conservation of linear momentum and the conservation of kinetic energy to create a third equation.  Any two of these equations now contain all the information, so the three equations are said to be linearly dependent in math-speak.  This means we only need to use any two equations for our solutions, naturally we will chose the simplest two.  (c) Use two of these equations along with…

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

you are with your father with his motorbike on the way to your school. In the middle of your travel, the gas was empty. Luckily there is a gas station nearby. Your father asked you to buy 2 liters of 100 worth of money per 2 liters "premium" gasoline advertised with r=13. But you choose to buy a 93 worth of money per 2 Liters ordinary fuel with r=8. (a) how much decrease in the ideal efficiency results from this decrease in the compression ratio? Use y=1.40. (b) Is it greater than the difference in price?

as an aerospace engineering student, where do you utilize flight simulators?

Question 7 The following formulas are commonly used by engineers to predict the lift and drag of an airfoil: where L and Dare the lift and drag forces, V is the airspeed, S is the wing span,  is the air density, and CL and CD are the lift and drag coefficients. Both CL and CD depend on α , the angle of attack, the angle between the relative air velocity and the airfoil’s chord line. Wind tunnel experiments for a particular airfoil have resulted in the following formulas.   where α is in degrees.

Scenario 1 Your boss, Melon Usk, wants you to determine the acceleration of his new car. The details of the car are as follows: The car's total mass is 1500 kg The motor outputs a constant torque of 300 Nm The drive train has a gear ratio of 10:1 to the drive axle Prior to any gearing, the motor and drivetrain have a moment of inertia of 0.5 kg m². The four tires are 0.6 m in diameter. A single set of final gear, drive axial, and tire has combined moment of inertia of 0.6 kg m². Not knowing how to proceed, you e-mail your favourite ex-instructor, Frank. He is very busy but draws you the following: ● ● ● ● ● ● Motor ● FT+ IM = 0.5 kg. m² TIN = 300Nm TIN Final Gear + Wheel Wheel RG Final Gear C Rw Fw Iw = 4(0.6 kg m²) = 2.4kg. m² RG = 10R Rw = 0.3m Car Fw m = 1500kg y x Frank also notes the following: You can treat all four tires, axels, and final gears as a single entity. The moments of inertia will add together but the radius will remain the same. You do not need to know the complex…

As far as maintenance costs are concerned: O for high levels of maintenance commitment, breakdown maintenance costs exceed preventive maintenance costs. O for low levels of maintenance commitment, preventive maintenance costs exceed breakdown maintenance costs. preventive maintenance is always more economical than breakdown maintenance. breakdown maintenance is always more economical than preventive maintenance when the "full cost of breakdowns" is taken into consideration. O for low levels of mairtenance commitment, breakdown maintenance costs exceed preventive maintenance costs.

APPLICATIONS OF FIRST ORDER DIFFERENTIAL EQUATIONS Newton’s Law of Cooling and Joint Proportions   At 4:00pm, a thermometer reading of 28 deg C is taken outside where the ambient temperature is –11 deg C. At 4:05 pm, the thermometer reads 8 deg above zero. After a while, the thermometer is returned to the room maintained at 28 deg C. At 4:12pm, the thermometer reads 15 deg C. When was the thermometer returned to the room?

February 7, 2021 H.W MECHANICS PHrsics Example 5.13 Friction in horizontal motion You want to move a 500-N crate across a level floor. To start the crate moving, you have to pull with a 230-N horizontal force. Once the crate "breaks loose" and starts to move, you can keep it moving at constant velocity with only 200 N. What are the coeffi- cients of static and kinetic friction? Example 5.15 Minimizing kinetic friction In Example 5.13, suppose you move the crate by pulling upward on the rope at an angle of 30 above the horizontal. How hard must you pull to keep it moving with constant velocity? Assume that H = 0.40. Example 5.16 Toboggan ride with friction I Let's go back to the toboggan we studied in Example 5.10. The wax has worn off, so there is now a nonzero coefficient of kinetic friction 4. The slope has just the right angle to make the toboggan slide with constant velocity. Find this angle in terms of w and Hg. Example 5.17 Toboggan ride with friction II The same toboggan with…

9. You are responsible for developing a new low-altitude (<100 m max. altitude), subsonic, land attack cruise missile. The Program Executive Officer (PEO) received his training in the 80's. He demands that [the missile] use an "all-weather" altimeter (implying an existing 17-GHz radar altimeter). You know that this device can be detected, localized, identified, and tracked by a new generation of threat-owned, netted, radio-frequency interferometers. As a result, most of the missiles can be easily detected, targeted and downed. Tactfully explain to the PEO why the legacy 17 GHz altimeter can be easily detected and tracked and propose an alternative altimeter/sensor system to the PEO that addresses that issue and justify its ability to meet requirements, including his "all-weather" capability.
