A uniform rod rotates about a perpendicular axis through one end, in a gravity-free region. Which graph gives stress against distance from the axis?

Answer:

Solution:

$T (x) = \int_{x}^{ℓ} ρ A ω^{2} s d s$ .

$σ (x) = \frac{ρ ω ^{2} ( ℓ ^{2} - x ^{2} )}{2}$ .

The curve is a decreasing concave-down parabola.
