Rotational stress in a bar – V.MohanKumar

Rotational stress in a bar

(Strength of materials – by Er. R.K. Rajput)

l: length of the bar;

ρ: density of the bar;

ω: angular velocity

From the above formula, the stress developed by the bar due to rotation can be calculated. This formula is generally used in vibration analysis of a shaft connected between two gears.
