6. The steering used here is based on the RACK AND PINION principle, for effective steering and to avoid high steering ratio and the need for tires to slip sideways while following the path around a curve. Wheel Base (l) = 1143 mm Track Width Front (w) = 1054 mm Steer angle of the inner wheel= 22.5 Steer angle of the outer wheel =16.57 Steering ratio = 6:1 Tangential force to be made in the steering wheel by the driver to turn the wheel, T = 11.77 N TIE ROD SPECIFICATION LINE DIAGRAM OF THE STEERING DESIGN All dimensions are in mm All dimensions are in mm

7. Type of brake: DISC BRAKE DIMENSIONS OF THE BRAKE SYSTEM Apache RTR 40 mm dia Caliper Caliper diameter= 200 mm Caliper piston diameter= 40 mm Master cylinder diameter D= 19.05mm Rolling Radius of Tire= 0.1296 m Max force applied at the pedal= 20 kgf Pedal ratio= 4:1 Apache RTR 200 mm dia Disc Piston diameter - 19.05mm Master cylinder Dot 4 Fluid BRAKE FORCE ANALYSIS: Force required to make tires skid = Rrear * (Rtyre / Rrotor) =500.278 *(0.1296/0.1) =648.36 N Radius of brake pad rp= 20mm Area of the brake pad =2 * rp2 =2.51 * 10 Pressure applied =force/area =258.310 Maximum allowable pressure on steel rotor = 2680 Factor of safety = 2680/258.31 = 10.375 Therefore, the System is Safe.

10. TYRES AND WHEELS Tyres form one of the most integral parts of the go-kart as they are in contact with the road surface all the time. Hence a go-kart tire that provides enough traction, so as to transmit the torque available at the wheels without causing slipping need to be selected. Hence MRF ZW3 GOKART tires with following specifications are selected and as follows.
