1. This is due to the stress concentration at the corners of the key way and reduction in the cross-sectional area of the shaft. It, other words the torsional strength of the shaft is reduced.
2. In case the key way is too long and the key is of sliding type, then the angle of twist increased.
So it is actually assumed that the strength of the keyed shaft is 75% of the solid shaft.

What is a keyed shaft?
A keyed shaft or Keyway is method, based on a machined keyway in shaft, to attach something to the shaft and associated bore. A fitted key is inserted into a slot that is machined into the shaft.

What is the effect of shampoos on the tensile strength of hair?
Shampoos can temporarily weaken the tensile strength of hair by stripping away natural oils and proteins, leading to breakage and damage. However, using a moisturizing or strengthening shampoo can help maintain or improve hair's tensile strength by nourishing and protecting the hair shaft.
