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…

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…

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.

Analysis and Interpretation of vertical Ground Reaction Forces. In this study, a volunteer was asked to walk on two force platforms under two different conditions. Condition 1- Normal Walk (NW), condition 2 - walking over an obstacle (ObsW). The right limb was the one to step on platform 1 in both conditions. The force platforms were used to measure the vertical ground reaction forces on the right limb. Data was collected on Vicon (Nexus) software and the attached graphs ( mean NW/ObsW, Mean (+-)1SD NW/ObsW) were created. Analyse ,Interpret the graphs and make a conclusion of the result attached.

Simulated Annealing How would Simulated Annealing perform if the temperature, T, is always equal or very close to 0, where we omit the termination test (except that we terminate the search when a goal node, either a local or global optimum, is met)? Please pick up one option from the following options and explain.(a) A random walk(b) Hill-Climbing(c) It would halt immediately(d) It would never halt

Hello I have two pictures with some questions Id like to get answers to! Short and great explanations please thank you !

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?

Problem #2) A 155.3 slg SUV plows into the rear of a 68.32 slg sportscar. The collision was perfectly plastic; there was no bounce observed. Just before the collision the SUV was traveling at 29.3 ft/s, and the sportscar was stationary. The entire collision takes 0.3 seconds. a) What are the two vehicles' speeds, v'suv and v'sc, immediately following the collision? b) What average accelerations, asuv and asc, do the two vehicles experience? lost m = 155.3519 Suv m = M 68.32 sig sp V29.3 ft/s Suv V = 0 ft/s Sp t = 0.35 plastic: energy e=0

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

Mechanical Advantage Review Directions: Use the appropriate equation to answer the following questions. All answers should be recorded below or in your engineering design journal. Remember to show all work. 1. A lever has an effort arm that is 8 meters long and the resistance (load) arm that is 5 meters long, how much effort is needed to lift a 200 Newton weight?

For my assigment, I was asked to design a electric motorbike that has a peformance equal to Honda CBR1000 Fireblade which has a petrol engine. A part of the the assignment is to calculate " An estimate of maximum Power your new motor will need to generate to match the Honda’s performance." I can make the assumption, apart from changing the motor, everything else is going to stay the same so the fairing,the rider and etc they're gonna be the same for the two bikes. So can you please tell me how I can calculate that which information would I need ?
