Mechanical engineering thermodynamics. Handwritten solution accepted. (3-150) In an article on tire maintenance, it is stated that tires lose air over time, and pressure losses as high as 90 kPa (13 psi) per year are measured. The article recommends checking tire pressure at least once a month to avoid low tire pressure that hurts fuel efficiency and causes uneven thread wear on tires. Taking the beginning tire pressure to be 220 kPa (gage) and the atmospheric pressure to be 100 kPa, determine the fraction of air that can be lost from a tire per year.

Thermodynamics deals with forms of energy and change in the total energy of a system which can be assigned a value of zero at some reference point. The total energy of a system has two groups: macroscopic and microscopic. Describe the concept of macroscopic and microscopic forms of energy in a thermodynamics system. (d) A quantity of matter or a region in space chosen for study is referred to system. Some thermodynamics relations that are applicable to closed and open systems are different. It is extremely important to recognize the system before start analyzing it. Thus, differentiate among following thermodynamics systems. (i) Isolated system; (ii) Rigid system; and (iii) Adiabatic system.

QUESTION 10 A Watt (W) is defined as one Joule (J) of energy per second (s): 1 W = 1 J/s. It is also possible to calculate the watts of an electric device by multiplying the voltage supplied, in Volts (V), by the current drawn, in Amps (A): 1 W = 1 V x 1 A. Consider an electric car with a 75 kWh (kilowatt- hour) battery. If the car consumes on average 230 Wh/mile, what is the maximum range of the car in miles? Enter your answer to one decimal place using rounding.

You have been asked by your supervisors at A&L Engineering to design a roller coaster for a new theme park. Because this design is in the initial stages, you have been asked to create a track for the ride. Your coaster should have at least two peaks and two valleys, and launch from an initial height of 75 meters. Each peak and valley should represent a vertical change of at least 20 meters. In your design, you should plan for a mass between 400 and 600 kilograms. Once you have designed the track, you have been asked to calculate the kinetic energy, potential energy, momentum, and work done by the cart at various points throughout the track.

1) A small steel block and a magnet rest on a horizontal frictionless table. The steel block weighs 0.07N and the magnet is fixed to the table. The force acting on the steel block by the magnet is inversely proportional to the square of the distance between the steel block and the magnet. When the block is 26cm away from the magnet, the force becomes 0.145N. If the block starts its motion from rest at this position, what is the magnitude of the velocity of the block when it is 9.5cm away from the magnet?

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…

Q1. Newton's second law is valid for an observer attached at the inertial frame. Usually, we make the approximation in using Newton's law calculating accelerations with respect to an observer on earth. Although -strictly speaking, this is wrong- the error made is often negligible. But how much of an error do we really make in using these assumptions? Are they really negligible? The questions below will help you find the answer. Assume an aircraft flying from Istanbul straight south to Cape Town, South Africa at a constant speed of 800 km/h. (Fig.1) a. What is the average acceleration the aircraft will have due to earth's curvature only in order to maintain constant altitude? b. What is the average acceleration due to the earth's curvature and earth's rotation around combined in order to maintain constant altitude? (Assume perfect sphere, neglect rotation around sun) Hint: You may calculate the acceleration by attaching a coordinate system at the airplane (Tangential and normal…
