Help!!! Please answer part B correctly!!! Please

A Team of Engineers asked for an internal combustion engine to use it in a designed car. Your role is to describe the operation sequence of different types of available engines, explain their mechanical efficiency, and deliver a detailed technical report to show your approach in solving and discussing the following tasks and issues.  You must follow the following steps to help the team:  STEP 1  Describe the operational sequence of four-stroke spark ignition and four-stroke compression ignition engines with the aid of sketches by constructing simple sketch representing the operation and plotting the P-V diagrams for each process during the cycle to show the following:  The input and output heat and net output work The expansion and compression strokes The air-fuel mixture intake and exhaust gasses The spark plug when it is in the active mode The complete cycle of ideal Otto and Diesel cycles that shows the input and output heat and net output work. STEP 2  Explain the mechanical…

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…

Design for an infinite life by finding the appropriate thickness of the vessel to carry a sinusoidal pressure varied from {(-0.1) to (6) Mpa}. The vessel is made from Stainless Steel Alloy-Type 316 sheet annealed. The operating temperature is 80 C° and the dimeter of the cylinder is 36 cm. use a safety factor of 1.8. Fig. 1 (15 Marks) Q2/ Answer the following: 1- Derive the design equation for the direct evaluation of the diameter of a shaft to a desired fatigue safety factor, if the shaft subjected to both fluctuated…

5. Describe enthalpy of formation. Please select all answers that apply: a) Standard enthalpy of formation is the amount of change in enthalpy evolved during the formation of 1 mole of the substance from its constituent elements with all elements in their standard states. b) Standard enthalpy of formation is the energy associated with chemical bonds. c) Standard enthalpy of formation is the amount of change in enthalpy evolved during the formation of 100 moles of the substance from its constituent elements with all elements in their standard states. d) Standard enthalpy of formation is the amount of change in enthalpy evolved during the formation of 1 Kg of the substance from its constituent elements with all elements in their standard states. e) Standard enthalpy of formation is the energy associated with heat transfer.

Question 2 You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial weight bearing activities. Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the yield stress for the…

- Explain how each of these variables relate to environmental impact assessment and how they affect the concentration of a pollutant released by an action in the environment temporally or spatially:  time, source, receptor, convection, dispersion, reaction.For example: time ‐ time is the duration over which the impact assessment is modeled, and extends from 0 before the action (existing condition) to some time in the future after the action has occurred (impacted condition); time affects concentration for unsteady problems.

dear tutor please provide neat and clean and detailed answer. dont copy from google adress both questions well

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

Technical graphics are the preferred method for communicating designs during a design process. True False

Topics: Statics of Rigid Bodies, Equilibrium of Rigid Bodies, Equilibrium in Two Dimensions, etc.   I will rate you with “LIKE/UPVOTE," if it is COMPLETE STEP-BY-STEP SOLUTION.   If it is INCOMPLETE SOLUTION and there are SHORTCUTS OF SOLUTION, I will rate you with “DISLIKE/DOWNVOTE.”    THANK YOU FOR YOUR HELP.   PS: If you have answered this already, don’t answer it again; give chance to other experts to answer it. I want to verify if all of you will arrive in the same final answer; thats why I ask it multiple times. If you answer it again, i'll dislike all your entries/answers.
