A two-wheel drive tractor is fitted with driving wheels having rolling radius of 860 mm. The effective gear ratio between the engine to the drive wheels is 98:1 and the power transmission efficiency at that gear ratio is 86%. If the engine torque is 520 N m, the ground thrust developed by the drive wheels in kN is __________. [round off to two decimal places]
Official Answer Key:
50.95 to 50.97
Step-by-Step Solution & Explanation
• Wheel torque = 520×98×0.86 = 43,825.6 N·m
• Ground thrust = 43825.6/0.86(radius in m) = 50,960.0 N = 50.96 kN
Computed value: 50.96 kN (within official range 50.95–50.97)
