Downloading "patched" software is a violation of copyright law. For engineering students, this sets a poor precedent for professional ethics. For professional engineers, using unlicensed software can lead to liability issues if the designs produced are ever audited or challenged in court.
Consider purchasing the book directly. While this isn't a free option, it ensures you get a legitimate copy and any accompanying digital resources.

Terms like "English patched" typically refer to unofficial, user-translated versions of software or PDFs. While these may exist in niche online communities, they are not legitimate publications and often violate copyright laws. Official Access & Alternatives
If you are looking for the content of this reference work in English, you have several reliable options:
Official German Digital Versions: You can purchase and download the official PDF of the German edition (e.g., the 27th Edition) from Springer Nature. Modern PDF readers can perform Live Translation on these documents to help you navigate the technical German.
MDESIGN Roloff/Matek Edition: This software integrates the calculations and standards from the book into a digital environment. While the software itself may have English interfaces, it is designed for students and professional designers to apply the book's formulas directly
English Equivalent Textbooks: For comprehensive machine element design in English, experts often recommend: Shigley's Mechanical Engineering Design
: Often considered the English-language "Bible" of machine elements. Machine Elements in Mechanical Design by Robert L. Mott. Dubbel - Handbook of Mechanical Engineering
: A massive German reference that does have an official English translation, though it is less frequently updated than the German original. Managing a German PDF
If you must use the original Roloff/Matek PDF, you can use these tools to bridge the language gap:
DeepL or Google Translate: Upload the PDF (if size permits) to these services for a full-document translation.
OCR Tools: If the PDF is a scan, use Acrobat or Online OCR to make the text searchable and copyable for quick translation of technical terms.

For those requiring native English materials with a similar breadth of design principles and calculation methods, these textbooks are widely recommended:
Machine Elements in Mechanical Design (e.g., by Robert L. Mott)
: A comprehensive resource covering materials, stress analysis, fasteners, gears, and bearings. Shigley's Mechanical Engineering Design
: Considered the standard English-language equivalent, focusing on failure prevention, machine components, and detailed design methodologies. Mechanical Design of Machine Elements and Machines
: Offers a perspective on failure prevention and practical engineering methods. Universitas Pertahanan Key Topics in Roloff/Matek
The textbook is renowned for its vast selection of design principles, often providing dozens of ways to solve a single engineering problem (e.g., shaft-to-hub joints). Major sections include: Roloff/Matek Maschinenelemente
Searching for " Roloff/Matek Maschinenelemente " often leads to academic resources, but finding an "English patched" version is complex because the series is primarily published in German. Roloff/Matek Maschinenelemente
is a foundational German engineering textbook on machine elements, known for its extensive collection of formulas and standardized calculation methods.
Original Publication: The book is published by Springer Vieweg and is currently in its 26th edition (2024). It is widely used in German-speaking universities and is considered the "bible" of machine design. Chapter 5 – Springs Spring stiffness [ k
English Language Status: There is no official full English translation of the modern editions of this textbook. However, many of its tables and formulas use international ISO standards, which are accessible in English.
"English Patched" Content: The term "English patched" typically refers to unofficial community translations or "fixes" often found on forums or file-sharing sites. These are frequently distributed as PDFs where technical terms or headers have been translated into English to help non-German speakers navigate the calculation tables.
Academic Use: International programs in Germany, such as those at TH Köln or Hochschule Rhein-Waal, often list the German version as recommended reading but provide lecture notes or supplementary materials in English to bridge the gap. Alternatives for English Speakers
If you need the technical rigor of Roloff/Matek but require English content, consider these standard English-language textbooks: Shigley's Mechanical Engineering Design
: The most common English equivalent for machine elements and design. Norton's Machine Design: An Integrated Approach
: Focuses heavily on the practical application of machine elements.
German-English Engineering Dictionaries: Many students use the original German Roloff/Matek alongside a technical dictionary, as the formulas and diagrams are largely self-explanatory once you understand the nomenclature. Module Catalog Vehicle Development - TH Köln
Chapter 5 – Springs
Spring stiffness
[ k = \fracG, d^48, D^3, n ]
Where:
• G – Shear modulus of the material (Pa)
• d – Wire diameter (mm)
• D – Mean coil diameter (mm)
• n – Number of active coils (dimensionless)
Design tip: For steel springs, use a safety factor of 1.5–2.0 on the calculated stress to accommodate surface fatigue.
Such an overlay typically also replaces German standard references (e.g., “DIN 6180”) with “ISO 23515 – Spring Design” where applicable.
The work you are looking for is not a short academic paper, but rather a comprehensive standard textbook used in German engineering curricula.
Kapitel 5 – Federn
Federsteifigkeit k = (G·d⁴) / (8·D³·n)
Wo: G = Schermodul, d = Drahtdurchmesser, D = mittlerer Windungsdurchmesser, n = wirksame Windungszahl.
