Navy back to Sextant

When I was starting on my MBA I checked about skipping the math courses: they asked if I used Calculus in my day-to-day work and weren’t amused when I told them, “Nobody uses Calculus in their work.” Other than a waste of time and money (was reimbursed), the Statistics & Matrix Math courses were a nice refresher (no Calculus).

I agree 99% never use Calculus after college

I use Math up to Calculus a lot when working doing engineering.

But I think in reality only about 99% never use Calculus after college.
Most just wast of time.
I have ask license Engineers that question and all said same thing only used algebra.
It is not some ever need.

What did I could not go and buy off the shelf. For my work there no charts or tables for parts
So I had figured out what was need then make the part.
Some parts took up to 5 pages for others to read.
I forgot how many pages a job would have.
----------------------------------------
I have look at some jobs that my competitors use through and pray engineering. They heavy plate then why.
----------------------------------------
I found in different industry the engineer said they extra heavy to keep the cost of license engineering cost down. Basically he did could not do any engineering but on he had a degree from a college for engineering.
----------------------------------------
I never do a job without doing all the engineering first. It one best butt covers any can do.

Large ships use multiple shafts to get the necessary Hp into the water, also for redundancy. Smaller and auxiliary ships typically have one.

Yes, with multiple shafts you can “steer” a ship without using the rudder, but it is not practical for anything other than limping around.

I was to see supper size with screw.
I am say all but I seen just one

Cargo ships, like the Dali that struck the Key Bridge, typically have one screw: don’t need quick response or high speeds, just go in straight lines. The Dali displaces 149,000 t, is 984’ long and has 55,630 Hp. In comparison, the USS George H. W. Bush (CVN77) displaces 114,000 t, is 1,040’ long (waterline) and has 260,000 Hp.
