Why are flat keys more stable than the square keys in the design of shafts?
Can you explain why flat keys are considered more stable than square keys in the design of shafts?
Of course! Flat keys provide greater surface area for contact with the shaft, which results in better distribution of the torque load. Square keys, on the other hand, have corners that can act as stress concentrators, leading to failure under heavy loads.
