| X3441 DETAILS OF EAC-1 STEERING. V3441 X9940 X4578 Effective tyre dia. to give true centre point steering = 35.7". Actual effective tyre dia. in practice taken as 33". Deviation in centre point due to this = .228". Torque tending to deflect the steering when one wheel locked on a road, - load on front axle 22 cwts., co-efficient of friction .6" = 740 X .228 lbs.ft. / 12 = 14.1 lbs.ft.
