Shaft A and B are connected through gear drive. Shaft A runs at 100 RPM at with a torque of 200 N M. What is the torque in shaft B if it runs at 400 RPM

  1. 800 N m

  2. 200 N m

  3. 500 N m

  4. 50 N m

D Correct answer
Explanation

Power is conserved across gears: P = T × ω (torque × angular velocity). Since ω doubles (100 to 400 RPM), torque must halve. TB = TA × (100/400) = 200 × 1/4 = 50 Nm.
