<br />Straight Truck or Tractor <br />Turning Radius: Solutions <br /> <br />d <br /> <br /> <br />e <br /> <br />c <br /> <br />Front of <br />_ Straight <br />Truck or <br />Tractor <br /> <br />b <br /> <br />Terms <br /> <br />Symbol <br /> <br />Track <br />TR <br />TA <br />WB <br /> <br />Shown On Chart As <br /> <br />be, cd <br />ae <br />Angle B <br />be, de <br /> <br />Track <br />Turning Radius <br />Turning Angle-I nside Wheel <br /> <br />Wheelbase <br /> <br />a <br /> <br />TR Solution #1 <br /> <br />Turning Radius = Wheelbasa'sine Angle A = de/sine Angle A <br />Cotangent Angle A = Track/Wheelbase + Cotangent Turning Angle be/de + Cotangent Angle B <br /> <br />Example: Given: WB = 19B, Track = 77, TA = 300 <br />CotangentAngleA = 77/198 + 1.7321 = 2.121 <br />From Table of sines: Sine angle A = .42646 <br />Turning Radius = 1981.42646 = 464.3 inches <br /> <br />TR Solution #2 <br /> <br />Turning Radius = ae = V(ad)2 + (de)2 <br />ac = cb sineC/sineB <br /> <br />where de = WB, ad = ac + cd where cd = Track <br />where cb = WB, Angle B = T A, Angle C = 900 .
