I need a detailed modal analysis carried out in ANSYS Mechanical (Workbench or APDL) on a composite beam that is mounted on linear springs at both ends. The study is part of my master’s research, so every modelling choice—from element selection and mesh sensitivity to boundary condition justification—must be fully traceable. Two configurations must be investigated: 1. The bare beam on linear springs. 2. The same beam on linear springs with a centrally-mounted lumped mass (a disc). I already have the exact beam dimensions and material properties for the composite lay-up; I will share them once the project starts. What I require from you is to import or build the geometry, assign the composite stack, model the linear spring supports correctly, and extract natural frequ...

I have a mechanical engineering assignment that includes stress-strain relationships, beam bending, shear-force diagrams, torsion of shafts, and basic dynamics. The section giving me trouble is the basic dynamics portion—kinematics, kinetics, and energy/impulse-momentum methods for particles and rigid bodies—and I need clear, step-by-step help so I can understand the reasoning as well as present polished solutions. The task is to work through the provided problem set, show every calculation cleanly, annotate free-body diagrams, and highlight the governing equations used at each step (Newton’s laws, work-energy, impulse-momentum, etc.). Please keep notation consistent with standard mechanical engineering texts, and include brief commentary on common pitfalls so I can lear...

I want to bring a small, ESP32-powered toy drone from concept to first lift-off. The goal is purely recreational: a fun flyer that can be controlled from a smartphone rather than a conventional RC transmitter. Core functionality must include reliable auto-stabilization so even a beginner can keep the craft level. Here’s what I already have in mind: • Flight controller: ESP32 (your choice of dev-kit or custom PCB) • Sensors: a compact 6-axis IMU such as MPU6050/ICM-20689 for attitude data • Motors & ESCs: typical micro-quadcopter class, but I’m open to your sizing suggestions • Firmware environment: Arduino IDE or ESP-IDF—whichever you can deliver faster and maintainably • Mobile control: a lightweight Android/iOS app communicating via...

I am developing a new spectacle frame and need a product designer who can balance engineering accuracy with eye-catching style. Both the mechanical function and the overall look carry equal weight for this project, so I’m counting on you to finesse every detail—from hinge geometry to surface curves—until the piece is production-ready and commercially appealing.

I am developing a space-saving cable machine for modern fitness studios and I need a complete mechanical design that turns the concept into production-ready files. The unit must let users perform at least leg curls, and the highest priority on the user side is an effortless adjustable-height mechanism. Above all, I have to be certain the base will remain rock-solid and safe under every condition; stability is the single most critical aspect of the build. Core performance targets • 120 kg adjustable weight-stack resistance driven by a low-friction pulley network. • Structural steel or aluminium frame whose worst-case deflection stays below 2 mm with a global factor of safety of 2.5 or higher. • Optimised pulley diameters, cable routing and bearing selection to keep tra...

Hello, We have completely redesigned the machine concept and working methodology. The new approach is aligned with a regular bean-to-cup coffee vending machine, upgraded for specialty coffee output with dual ordering capability (two drinks simultaneously) using two displays and two side-by-side cup dispensing stations. The system has been simplified significantly by removing CNC/gantry, conveyor, and robotic mechanisms, and is now based on a static modular architecture with pump + pipe-based fluid delivery. --- UPDATED SYSTEM OVERVIEW: • Dual cup dispensing system (left & right) • Two independent serving positions for parallel output • Two user interfaces (dual ordering screens) • Centralized internal modules: - Coffee grinder + automatic brew group (piston-...

I need a technically sound bracket that mounts a light bar on the integrated roof rails of the SKODA ENYAQ and other recent SKODA SUVs. Because these rails are closed, the solution must grip from above—no under-rail hardware is possible. Key requirements • Material: steel for strength and longevity. • Attachment: a clamping mechanism that hugs the rail profile without marring the factory finish. • Feature: an integrated quick-release so I can fit or remove the light bar in minutes. What I’m looking for 1. Accurate CAD models and fabrication drawings based on real-world rail dimensions (preferably gathered by you or sourced from verified databases). 2. An assembly guide that shows the clamping process step by step. 3. Suggestions on fasteners, surface tr...

My new-construction home in California (just over 4,000 sq ft) needs a complete HVAC design package. The concept I want to pursue is a dual heat-pump arrangement paired with a passive cooling strategy; beyond that, I’m relying on solid load calculations to dictate exact equipment selection, whether that ends up being Carrier, Trane, Lennox, or another equivalent line. Here’s what I need from you: • Full heating and cooling load calculations that respect California climate data and Title 24 requirements • Sizing and selection of two coordinated heat-pump systems plus any ancillary components required for passive cooling integration • Ductwork layout, airflow balancing, and equipment schedule ready for my architect and builder to drop straight into the permit...

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 need a complete finite-element model of a Warren through truss bridge built in ANSYS (Workbench Mechanical or APDL). The task covers geometry creation, material assignment, boundary conditions and, most importantly, a dynamic study that captures wind and traffic effects. For wind, please implement a realistic fluctuating pressure profile; for traffic, model moving axle loads that travel the bridge length with appropriate speed and spacing. Time-history or transient structural analysis is preferred so that true stress-strain and displacement histories can be extracted. I have only a broad idea of where sensors should sit—mid-span, panel points near supports, and a few along the top chord—so I will rely on your structural-health-monitoring experience to pin down the exact n...

I already have an ESP32-C3 prototype of AutoSmear running reliably on a hand-wired board, but now it is time to turn that lab-bench tangle into a production-ready PCB. Compact layout is my top priority: the board must fit inside the existing enclosure while leaving room for future shielding and airflow. Just as important, the A4988 motor driver needs to be integrated cleanly so the stepper that moves the blood-film spreader glides without vibration or jerks. What I will hand over to you • Tested firmware ( ESP32-C3) • Current schematic, wiring diagram and BOM • Mechanical constraints for board outline and mounting points What I need back • Updated schematic reflecting any refinements you suggest • Space-efficient multilayer PCB layout with proper ground...

I need a mechanical design engineer who can turn my concept for an industrial hydraulic tilting table into a complete, fabrication-ready package. The table must safely handle heavy loads over 2 000 kg while tilting through 0–45 °, and its movement has to be managed by a fully automatic hydraulic control system with position feedback, safety interlocks, and a clean operator interface. The schedule is tight: I’d like to kick off immediately, see a first concept layout within a few days, and iterate rapidly to final approval. Throughout, I expect solid adherence to ISO/ASME standards, careful attention to weldment rigidity, and documented strength calculations that demonstrate an adequate factor of safety at every tilt angle. Deliverables • 3D CAD model (SolidWorks or I...
