Problem

A cylindrical water tower has developed a concerning

15°

lean due to foundation settling. The tower has a height of

h = 20\;\text{m}

and radius

R = 3.0\;\text{m}

. When full, water reaches to within

2.0\;\text{m}

of the top. Engineers need to determine if the tower will tip over when full. The empty tower (steel structure only) has a mass of

M = 8.0 \times 10^4\;\text{kg}

with its center of mass located

12\;\text{m}

from the bottom. The tower is anchored at its base, which forms the pivot point. (a) Find the horizontal distance from the pivot point to the combined center of mass of the tower-plus-water system when the tower is full. (b) What is the minimum coefficient of static friction

\mu_s

between the tower base and foundation required to prevent the tower from sliding horizontally?
