Redndant Engineeringing take 2 (and 2.50)
To the optimist, the glass is half full. To the pessimist, the glass is half empty. To the engineer, the glass is twice as large as necessary.
Take 2.50: To the engineer, the capacity of the container has been over designed by a factor of approximately 1.905 assuming a 5% volume for the sloshing safety factor.
