Ratio of Torsional Strength of Shaft with Keyway to without Keyway Solution

STEP 0: Pre-Calculation Summary
Formula Used
Ratio of Shaft Strength = 1-0.2*Width of Key in Round Shaft/Diameter of Shaft with Keyway-1.1*Height of Shaft Keyway/Diameter of Shaft with Keyway
C = 1-0.2*bk/d-1.1*h/d
This formula uses 4 Variables
Variables Used
Ratio of Shaft Strength - The Ratio of Shaft Strength is a measure comparing the strength of a shaft to the applied loads, helping to ensure safe and effective machine design.
Width of Key in Round Shaft - (Measured in Meter) - The Width of Key in Round Shaft is the measurement of the key used to secure components in a round shaft, influencing load distribution and stress concentration.
Diameter of Shaft with Keyway - (Measured in Meter) - The Diameter of Shaft with Keyway is the measurement across the widest part of a shaft that includes a keyway, crucial for transmitting torque in mechanical systems.
Height of Shaft Keyway - (Measured in Meter) - The Height of Shaft Keyway is the vertical dimension of the keyway cut into a shaft, which accommodates a key for securing components and transmitting torque.
STEP 1: Convert Input(s) to Base Unit
Width of Key in Round Shaft: 5 Millimeter --> 0.005 Meter (Check conversion ​here)
Diameter of Shaft with Keyway: 45 Millimeter --> 0.045 Meter (Check conversion ​here)
Height of Shaft Keyway: 4 Millimeter --> 0.004 Meter (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
C = 1-0.2*bk/d-1.1*h/d --> 1-0.2*0.005/0.045-1.1*0.004/0.045
Evaluating ... ...
C = 0.88
STEP 3: Convert Result to Output's Unit
0.88 --> No Conversion Required
FINAL ANSWER
0.88 <-- Ratio of Shaft Strength

Stress concentration in brittle materials

The effect of stress concentration is more severe in the case of brittle materials, due to their inability to plastic deformation. Brittle materials do not yield locally and there is no readjustment of stresses at the discontinuities. Once the local stress at the discontinuity reaches the fracture strength, a crack is formed. This reduces the material available to resist external load and also increases the stress concentration at the crack. The part then quickly fails. Therefore, stress concentration factors are used for components made of brittle materials subjected to both static loads as well as fluctuating loads.
