A Horizontal Tank Has Ends in the Shape of an Ellipse

Short Answer

A horizontal tank has ends in the shape of an ellipse $4.00 \mathrm{~m}$ wide and $2.00 \mathrm{~m}$ tall. Find the force on one end to three significant digits when the tank is half full of oil (density $=961 \mathrm{~kg} / \mathrm{m}^{3}$ ). Recall gravity is $9.8 \mathrm{~m} / \mathrm{s}^{2}$ .
