Solving the Mechanical Steering Requirement of Solar Challenge

 In order to maximise efficiency while increasing hull capacity, no mechanical steering is provided.

I have sent an email to the World Solar Challenge admin but so far no reply. Initially, I though we cannot achieve this but I just realised that we can use differential braking to achieve the mechanical steering. https://aviation.stackexchange.com/questions/1750/what-is-differential-braking

This is used by a lot of aircraft when they taxi on the runway.

What is required is just two pedals for the left and right brakes, just like in aircrafts.

The question is whether car drivers can be as efficient in steering the car by using differential steering alone.

The regulation is not clear. It does not really make sense. The mechanical backup requirement should be just that, a backup. It does not need to be fully functional. I am not sure how to please authorities who are still backward in their approach to technologies.

A Short Guide To Metric Nuts and Bolts

Hit enter to search or ESC to close A Short Guide To Metric Nuts and Bolts Answers to the most Frequently Asked Questions Standard and Fine Pitch Threads How to identify nut and bolt strength grades How nut and bolt strength grades compare Maximum Tightening Torques Why specified torque is sometimes lower than the maximum Spanner Sizes Versus Bolt / Nut thread size Allen Key size versus Bolt / Nut thread size Correct Drill size for Tapping Metric threads in holes Introduction: Metric Nuts and Bolts This short guide is intended to give a very basic introduction to ISO metric nuts and bolts. It is intended for those working in plant and machinery maintenance to give enough information on to ensure that correct replacement parts are identified and used. Few parts are as critical in the assembly of modern machinery as the nuts and bolts which hold it all together and, at first sight, it seems that all metric bolts are basically the same. In fact, of course, nothing could be further from th...

CAN Bus Wiring Diagram, a Basics Tutorial

Image
https://tekeye.uk/automotive/can-bus-cable-wiring Index ↓ About ↓ CAN Bus Wiring Diagram, a Basics Tutorial The CAN bus is a common digital data network used in automotive, industrial, medical and scientific systems. The CAN bus is used for routing sensor data between pieces of equipment. The main advantages are high resilience to noise, reliability, low cost, simple wiring and ease of use. The disadvantages are that the data packet lengths are small, transmission rates are low and the message transmission cycle time can vary. This article covers the basics of CAN bus wiring, showing a simple CAN bus wiring diagram and how to wire up a CAN bus cable. It covers wiring for the common DB9 plug and socket often used with CAN bus test equipment. The DB9 is also known as 9-pin D-sub, DE-9 (its correct name), DB-9, serial connector, RS232 connector or null modem connector. The CAN bus is used in nearly every form...

Best Free CFD Tutorial: FreeCAD Openfoam CFD Workbench

Image
I find watching this video boring but the links are userful and the linked tutorial very helpful. Better than reading the instructiions in the FreeCAD Addon installation comments for CFDof. http://www.opensim.co.za/training.html   The tutorial that is useful in doing CFD for car is the one below: https://github.com/opensimsa/opensim/raw/master/Documentation/CFD/UAV2/CFD%20Tutorial%204%20-%20External%20Aerodynamics%20of%20a%20UAV.pdf   WINDOWS: ● https://www.freecadweb.org/wiki/Download ● Install CfdOF from Tools | Addon manager ● Go to Edit | Preferences | CFD to check and install dependencies   Of special note: I install the older version of Paraview as shown in the FreeCAD preferences. I downloaded cfmesh and HiSA from sourceforge. No need to look for binaries. It appears as though the master file  zipped file can be installed by FreeCAD.   cfMesh downloaded to C:\Users\othma\AppData\Local\Temp\tmpwg568v1r.zip Installing cfMesh... Install completed Download...
