Subtopic: Calculation of power, torque, fuel consumption, heat load and power losses
Question Statement:
When a tractor negotiates a sharp right turn in the field, the differential gear assembly ensures that:
Options:
(A) Both drive wheels rotate at identical rotational speeds
(B) The outer left drive wheel rotates faster than the inner right drive wheel while delivering equal torque
(C) The inner drive wheel receives all the engine torque
(D) The differential bevel pinions stop rotating on their cross-shaft
Answer Key:
B
Step-by-Step Solution & Explanation
The standard open differential delivers equal torque to both axle shafts while allowing the outer wheel to spin faster over a longer radius arc and the inner wheel to slow down.
