Determine the maximum external pull of the four gears

Reference no: EM13310393

Determine the maximum external pull, in each of the four gears, for a tractor with 23-hp, and a max speed of 3.6 mph in 1st gear and a efficiency of 92%. When it is operated over a haul road whose slope is +2.53%. The rolling resistance of the haul road is 650 lb/ton. The tractor weighs 23.9 tons.
1st gear = 3.6 mph
2nd gear = 6.40 mph
3rd Gear = 11.2 mph
4th gear = 19.3 mph
