The date of testing should only be after purchasing the tube. x The teams using carbon fibre composite material and carbon monocoque chassis required to x Prepare separate design report and analysis report. They are required to submit the reports for verification from technical committee before manufacturing. x Failing to produce the necessary documents for testing, a team could be penalized or disqualified for the entire event. The decision would be taken by technical inspector and organizing committee. 1.2.8.3 Welding Check Process: x Each person who makes any welded joint on any of the vehicle’s roll cage elements must personally make two welding samples (defined below), using the same materials and processes as used in the roll cage element welds. x All welding samples must be submitted at Technical Inspection. x Vehicles for which complete sets of welding samples are not submitted, or for which any of the welding samples are judged inadequate, will not be allowed to compete in dynamic or endurance events. x Welding samples must be made from the same tube material, diameter, and thickness as the welds made by each person on the roll cage elements. x All weld samples shall be labeled by permanent means such as engraving, etching, or stamping with all of the following information: x College Name or College Initials x Welder Name or Welder Initials Sample 1 – Destructive Testing:  A 90-degree joint, the leg length is unrestricted. This joint must be destructively tested causing the joint to fail in the base material (as opposed to the weld metal). The testing method is free either tensile or bending failure may be induced; however, the peak stress must be located at the weld. In the case of bending failure, take care that the largest bending moment is located at the weld. Figure6 RollCage,WeldingSample1 Sample 2 – Destructive Inspection Two tubes joined at a 30 degree angle with a length of at least 150 mm (5.9 in.) from the center of the joint. The sample must be sectioned along the length of tube to reveal adequate and uniform weld penetration.

Main roll hoop: Adventure class- x Teams must provide a roll hoop behind the driver. Separating driver’s compartment from the rear of the vehicle. x The main hoop must be constructed of a single piece of uncut, continuous, closed section steel tubing x The use of aluminium alloys, titanium alloys or composite material requires proper analysis report. x The main hoop must extend from the lowest frame member on one side of the frame, up, over and down to the lowest frame member on the other side of the frame. x In the side view of the vehicle, the portion of the main roll hoop that lies above its attachment point to the major structure of the frame must be within ten degrees (10°) of the vertical. x Tip of the roll hoop should be at least 6 inches from tip of the helmet. The driver should be at rest while measuring. Professional class- x The roll hoop must cover both the drivers. x Tip of the roll hoop should be at least 6 inches from tip of the helmet. The driver should be at rest while measuring. x This will be measured by passing 6-inch diameter pipe horizontally from the top point of the helmet to right and left side of helmet. Figure11 DistancebetweenHelmet and Roll hoop B. Front roll hoop: Adventure class- x The front hoop must be constructed of closed section metal tubing x The front hoop must extend from the lowest frame member on one side of the frame, up, over and down to the lowest frame member on the other side of the frame.  x With proper gusseting and/or triangulation, it is permissible to fabricate the Front Hoop from more than one piece of tubing. x The top-most surface of the front hoop must be no lower than the top of the steering wheel in any angular position. x The front hoop must not be more than 250 mm (9.8 inch) forward of the steering wheel.

Some examples are- GFRP, carbon fibre, aluminum etc. x Outer body cover must run from front member to rearmost member, without any opening except those required for cockpit opening, cooling venting and kill switches. x As the vehicle is of closed wheel design, thus body works should cover the wheels. x The wheel should not hit the body during jounce or rebound while riding. x There should be no sharp edges/protruding edges on the outer body. x The solar panel should be secured so that no damage to the driver is done by it. x Bodywork should be detachable at different sections so that battery, transmission, steering, suspension and other components could be easily visible and reached at the time of Technical Inspection or maintenance. x Teams are to provide passage/slots for air to get in so that cooling of battery and motor can take place. This can be done by adding slot/opening at the side panel, as shown in the image below. This rule applies to both classes. x Bodyworks should be attached to the frame using fasteners and mechanical locks only. x Bodyworks should not be attached using nylon ties or any other tie straps. 1.2.10.2 Floor Closeout: x All vehicles must have a floor closeout made of one or more panels, which separate the driver from the pavement. x If multiple panels are used, gaps between panels should not exceed more than 3mm (1/8inch). x The closeout must extend from the foot area to the firewall and prevent track debris from entering the car. x The panels must be made of aluminium/steel. x Floor closeout should not be attached using nylon ties or any other tie straps. x Floor closeout should be attached to the frame using fasteners only. x Wooden ply and glass fibre will not be acceptable. 1.2.11 Stickers: 1.2.11.1 Vehicle Identification Number: Each car will be assigned a number at the time of its entry into a competition.
