Why didn't navigators on sailing ships just use a pendulum clock to keep time?

Pendulum clocks have a pendulum that moves, so on a moving ship the clock would not work right. The ships movement would throw off the clock telling the right time.


Why do captains have a tough time sailing close to the Equator?

Captains may have a tough time sailing close to the Equator due to unpredictable weather conditions such as calms and sudden storms. The Inter-Tropical Convergence Zone, known as the Doldrums, can cause periods of no wind, making it challenging for ships to make progress. Additionally, the Equator is known for intense heat and humidity, posing additional challenges for the crew and ship's machinery.


Why are the winds that blow from the subtropical high pressure zones in both hemispheres to the equator called trade winds?

In the era of sailing ships, regions of constant winds were much appreciated. They made trade around the world possible.


Did The Chinese developed a way to move the sails of ships that allowed ships to sail into the wind for the first time?

There is definitely two ways of doing things in this world; the Eastern (Oriental) way and the Western (Occidental) way. Eastern ships used square rigged sails whilst Western ships did not. It's now being discovered that the "ancient" Chinese may have sailed into North America (stone anchors have been found up some of the rivers in North America).It appears that both Oriental & Occidental mariners were capable of sailing into the wind. Who was first? Might have to experiment with some model ships: if the Chinese square rigged vessels can sail into the wind...then there's your answerANSWER: YesGot it right out of my social studies book.


How gyroscopic couple work in a aroplanes and ship?

Effect of the Gyroscopic Couple on an ship and Aeroplane :-Ships and aeroplanes consist of large moment of inertia propeller and fly wheels. When aeroplane or ship takes right or left turn there occurs a rate of change of angular momentum because of change of direction of angular momentum vector. Thus a counter couple is produced when they terns.When the engine or propeller of aeroplane or fly wheel of ship rotate such that the spin angular momentum vector is along the sailing direction and when the aeroplane or ship takes a left turn, then the effect of reactive gyroscopic couple will be to dip the nose (stem: for ship) and raise the tail of the aeroplane or ship.When the aeroplane or ship takes a right turn under similar conditions above, the effect of reactive gyroscopic couple will be to raise the nose and dip the tail of the aeroplane or ship.In the case of ships the fly wheel must be mounded such that the spin axis is along the length so as to maintain dynamic stability.
