Terms and conditions
Last updated 13 September 2026
By using this site you accept the terms below. If you do not accept them, leave the site.
What this site is
It is a personal record of engineering work by Arnav Kumar Lal. Nothing on it is an offer of professional engineering services, and nothing on it should be relied on as a design, a calculation or an approval for your own project.
Accuracy of the work shown
Every figure quoted on this site is taken from the report, drawing set or analysis it describes, and the corresponding document is published so you can check it. Results produced by simulation are simulation results. They are bounded by the assumptions, boundary conditions and material data stated in each report, and they are not a substitute for physical testing or for a licensed engineer's sign-off.
Copyright
The text, layout, drawings, models, analysis results and photographs on this site belong to me, except where they belong to the organisation the work was done for. You may read, print and quote short passages with attribution. You may not republish a document, a drawing or an image set as your own work, feed them into a training corpus, or use them commercially without written permission.
Documents published here
Certificates and letters were issued to me by the named organisations and are reproduced for verification only. Project reports and drawing sets are published with client identifying information removed where confidentiality required it. Some documents are held back for that reason, and a control marked as pending means exactly that. If you need a withheld document for a hiring decision, ask me directly.
Trade marks
Organisation names and marks that appear here, including DRDO, Honda Cars India, NSUT, the London School of Economics and 3D Paradise Technologies, belong to their owners. They are used to state factually where work was carried out. Their appearance is not an endorsement of this site by them.
Links out
Links to other sites are provided for reference. I do not control them and I am not responsible for their content or their availability.
Messages you send
Do not send confidential, classified or export-controlled material through the contact form. Anything you send is treated as ordinary correspondence. I reply to serious enquiries and ignore bulk marketing.
Availability and liability
The site is provided as it is. I do not guarantee that it will be available without interruption or free of error, and I am not liable for any loss arising from its use, to the extent permitted by law.
Governing law
These terms are governed by the laws of India. The courts at New Delhi have exclusive jurisdiction over any dispute arising from them.
