Concept explainers
To estimate: the angle at which levee floats.
Answer to Problem 2.7CP
Explanation of Solution
Given information:
Height of levee is
Width of levee is
Depth is
Density is equal to
Find the summation of moments with respect to hinge to find the value of angle
The forces acting on the levee are shown below,
Assume,
Density of seawater as,
Calculation:
The submerged length
Therefore, calculate the force
The submerged length
Therefore, calculate the force
Find the weight of levee,
Find the buoyancy force,
The average submerged length is equal to,
Therefore,
Calculate the moments about hinge,
Substitute for forces,
Solve to find angle
Conclusion:
The levee floats at an angle of
