STEERING DESIGN 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 LINE DIAGRAM OF THE STEERING DESIGN TIE ROD SPECIFICATION All dimensions are in mm All dimensions are in mm

BRAKING SYSTEM Type of brake: DISC BRAKE DIMENSIONS OF THE BRAKE SYSTEM 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 Caliper Apache RTR 40 mm dia Disc 200 mm dia Master cylinder Piston diameter - 19.05mm Fluid Dot 4 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 * π rp2 =2.51 * 10-3 m Pressure applied =force/area =258.310 kPa Maximum allowable pressure on steel rotor = 2680 kPa Factor of safety = 2680/258.31 = 10.375 Therefore, the System is Safe. STOPPING DISTANCE =3.528 M STOPPING TIME=0.94sec

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.

FRONT TIRES REAR TIRES Specification -150/270-2 tires Width – 80 mm Outer diameter of tire – 257 mm Outer diameter of rim – 5 inch REAR TIRES Specification -150/270-2 tires Width – 150 mm Outer diameter of tire – 270 mm Outer diameter of rim – 5 inch
