Why People Can Always Tell When AI Wrote Your Text
Young adults are letting ChatGPT draft their texts and hard conversations. Here's why it's obvious and what actually works instead.
Mechanical Design is a discipline of engineering that focuses on applying a combination of physical principles, mathematics, and materials science on the design, assembly, and maintenance of mechanical systems. The area often encompasses the development and analysis of both individual components and complete systems ranging from an entire car engine to smaller parts such as gears, levers, bearings, springs, hinges and other small mechanical parts. Mechanical Engineers use the knowledge and skills acquired to research, design, develop and test machines, engines and other types of tools for different industries. In essence, Mechanical Engineers create solutions that keep people and processes safe.
When working on projects for clients, hiring a Mechanical Engineer is beneficial for many reasons. A Mechanical Engineer offers expertise across multiple areas - engineering design skills to identify potential issues with existing systems or to develop new ones; problem-solving skills when it comes to resolving problems; knowledge in material sciences used in designing products; and the ability to develop detailed plans when implementing or maintaining systems. The expertise that Mechanical Engineers have makes them valuable assets to any business when it comes to creating effective solutions.

I need a fully parametric lower suspension control arm modeled in SolidWorks for an aluminum-alloy application that meets prevailing OEM standards. The part must include all typical features—mounting bosses, bushing housings, bolt holes, reinforcing ribs, generous yet realistic fillets, and thoughtful weight-reduction pockets—while maintaining structural integrity, manufacturability, and accurate fitment to the subframe. Once the 3D model is complete, I also require a production-ready 2D drawing that calls out every critical dimension, GD&T frame, hole specification, surface-finish note, and tolerance needed by a machine shop. Pay particular attention to clearance envelopes around bushings and ball-joint hardware so the arm drops straight into an existing chassis without r...

I am developing a portable outdoor golf entertainment game for the Australian market and require an experienced mechanical/product designer to develop the concept into a CAD and engineering package suitable for obtaining manufacturing quotations from China. The product is intended for backyards, camping, parks, BBQs, holidays and social events. It is an entertainment game rather than a professional golf training product. The current concept consists of a lightweight artificial-turf target board with four scoring holes. The board folds approximately in half for compact transport and storage and incorporates simple folding legs. Current approximate dimensions are: • Open: 900 mm × 550 mm • Folded: 450 mm × 550 mm • Target board weight: ≤3 kg if technically a...

I need a seasoned CAD specialist to turn a set of functional requirements and rough sketches into a complete mechanical design. The work will start in AutoCAD for clean 2-D layouts, then move into SolidWorks for fully constrained 3-D parts and assemblies. At this stage I’m keeping the exact component under wraps—think along the lines of a gear train, an engine sub-part, or a lightweight chassis—but the final brief will include all critical dimensions, tolerances, and performance targets. Your task covers the full modelling chain: parametric part creation, assembly fit-up, detailed drawings, and basic interference or stress checks so I can progress straight to prototyping or production without re-work. Native files are essential for future edits. Deliverables • Soli...

I’ve been working on an idea for a new consumer product for the last few months. I’ve got quite a long way with the idea but I’m going to be honest — I don’t really know what I’m doing when it comes to professional CAD! I’ve been trying to teach myself Fusion 360 and OpenSCAD as I go along. but I’m finding that I’m very slow and I’m probably making things much harder for myself than they need to be. I would now like the help of someone who has the knowledge and know-how to help me along. What I’m looking for isn’t just someone to make a quick model and disappear. I’d really like to find someone who could work with me over the project and help turn what I’ve got into a proper CAD model. The product is be...
I need a 3-D AutoCAD model of a toy tractor that feels and moves like the real thing, scaled for children’s play but engineered with professional precision. The project is strictly vehicle-based; no action figures or other toy types are involved. The design has to be highly detailed with full functionality: steering wheel connected to the front axle, rolling wheels, a hitch that can articulate, and any other realistic touches that make the tractor engaging when held in hand. Internal clearances, snap-fit joints, and parting lines should all be thought through so the file can go straight to tooling or 3-D printing without further rework. Additional Requirements: • Metal body construction. • Remote control functionality with three features: forward/reverse movement with le...
