I have homework for mechanics of machines with accelration polygon analysis

I need a fresh set of problem-solving questions that I can drop straight into an assessment for my Chemical Engineering Thermodynamics course. The focus is thermodynamic cycles only—Rankine, Brayton, refrigeration, combined cycles, the works—nothing on phase diagrams or heat-transfer calculations. Each question has to challenge an advanced undergraduate, so assume they already know the First and Second Laws, can read property tables, and are comfortable with ideal-gas and real-fluid analyses. Numerical answers must be attainable without exotic software; standard steam tables, refrigerant charts, or an EoS such as Peng–Robinson are fine. Deliverables • 8–10 original problems written in clear, exam-ready wording • Fully worked step-by-step solutions,...

I need a well-structured database of exam-ready questions and answers for my online paper-generator. The content must target MH CET, JEE and NEET and cover Physics, Chemistry, Biology and Maths.

I need a fresh bank of original maths questions that spans the entire KS3 and GCSE syllabus and mirrors the current Edexcel specification in tone, structure and level of challenge. This means everything from algebra and geometry through to statistics, number and ratio must be represented, with the difficulty ramping naturally from Year 7 foundations up to high-tier GCSE problem solving. For every topic I would like two distinct formats: multiple choice to check quick recall or reasoning, and short answer where students show a concise method or final value. I will handle any extended-response items separately, so please keep the focus on these two styles. Here is what I am expecting from you: • A clearly-organised question set, grouped by strand and sub-strand in the order Edexcel p...

I’m putting together a series of recorded math lessons for CBSE students in Grades 1-5 and need a tutor who can explain every concept clearly in both English and Tamil. The immediate focus is Geometry and Word Problems, but the explanations have to feel age-appropriate and engaging for younger learners. Here’s how I imagine the workflow: you prepare concise video lessons (roughly 10–15 minutes each) that walk through the topic step-by-step, demonstrate sample questions, and finish with a quick recap or mini-quiz the child can pause and solve before the solution appears. Because these are recorded sessions, strong audiovisual clarity and a friendly, encouraging teaching presence are essential. Deliverables (per topic and grade): • HD video file + any slides or vis...

I already have a working MATLAB model that generates particles, defines the micro-channel geometry, and steps the simulation forward, but the trajectories are drifting away from the intended channel centrelines. Your task is to bring those paths back into proper alignment with the device. What I need • Correct the alignment of particle trajectories by adjusting the entry points and modifying particle flow direction within the code. • Tackle the root cause: the current channel geometry parameters are influencing the solver in a way that deflects particles, so the fix must happen where those geometric terms are fed into the velocity field or boundary conditions. • Return a clean, well-commented .m file (or set of functions) that reproduces the corrected behaviour, plus ...

I have derived the governing equations for a rotating, pre-twisted blade treated as a thin shallow shell and now need a full modal vibration study. The formulation already includes the complete mass matrix, the gyroscopic matrix, and separate stiffness contributions for the structural shell, centrifugal stiffening, rotational softening, and an elastic root represented by spring constants. Thickness varies along the span, so any solution must respect the taper, the twist, and the elastic root support while the tip remains free. Your task is to compute the natural frequencies and mode shapes across a practical range of rotational speeds, capturing the combined influence of centrifugal force, Coriolis coupling, and rotational stiffening. Please work directly from the matrix form I provide, o...

I want a MATLAB-based system-level simulator that models Conditional Handover as well as L1/L2-triggered mobility in an integrated 5G terrestrial and satellite network. The sole purpose is performance analysis, so every module needs to expose parameters that let me compare handover success rate, latency, and throughput across a variety of mobility scenarios. The framework should let me define heterogeneous cells (gNBs and satellite beams), user mobility paths, channel conditions, and decision thresholds for conditional handover. Results must be traceable: at the end of each run I should receive time-stamped logs of mobility events together with aggregated KPIs and visual plots produced directly from MATLAB. Key functional points to cover • Support both 5G NR radio links and a repr...
