Q3: A train consists of a 400,000-lb locomotive and one hundred 200,000-lb hopper cars. If the locomotive exerts a friction force of 40,000 lb on the rails in starting the train from rest, compute the forces in couplers 1 and 100. Assume no slack in the couplers and neglect friction associated with the hopper cars. Ans.:T, = 39200 lb, T100 = 392 lb %3D

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 air-fuel mixture intake and exhaust gasses The spark plug when it is in the active mode
