Q2196991
Inglês
Captain Crenshaw, in his book ”Naval Shiphandling”, states that “Shiphandling is the art of handling the velocities of a
ship”. So, a pilot uses forces of engines, propellers, rudders, the wind and the tide, lines, tugs and anchors to control
the velocities of a ship.
One of the most important sources of force on a ship is her own propeller and the pilot must understand the action of a propeller in order to be able to predict its action on ship.
A propeller produces side forces in addition to thrust along the propeller shaft. A ship can rotates to starboard or port as function of these side forces.
Pilot Antonio is studying propeller side force, on a single right-hand screw propeller, and knows that it can be broken down in four parts: following wake effect, inclination effect, helical discharge effect and shallow submergence effect. Antonio wrote the following consideration:
I) The following wake effect produces a net force tending to move the stern to right and cause the ship to veer to the port.
II) The inclination effect is net effect that tends to twist the ship to the right.
III) The shallow submergence effect tends the stern to starboard and cause the ship to veer to the left.
IV) The helical discharge effect tends to turn the ship to the right.
From the list of Antonio is correct to affirm, according to the book “Naval Shiphandling”, that:

Q2196797
Inglês
In a single propeller ship going ahead, with a right-hand screw, as a blade moves downward it meets water which is
moving upward as well as aft. This is equivalent to _________________ the relative velocity and the angle of attack at
same time and thus, _________________ in thrust is experienced. On the opposite side, a ______________ in thrust
is experienced. The net effect of the reaction to the inclined flow, then, is a _________________ tending to
_____________the ship to the _____________.
According to R. S. Crenshaw, Jr., in the book “Naval Shiphandling”, which answer best fill in the blanks?

Read the extracts below and then answer the following questions.
TEXT 1:
Annual government surveys from the Bureau of Justice Statistics show no recent increase in the
U.S. violent crime rate.
In 2021, the most recent year with available data, there were 16.5 violent crimes for every 1,000 Americans
ages 12 and older. That was statistically unchanged from the year before, below pre-pandemic levels and far
below the rates recorded in the 1990s, according to the National Crime Victimization Survey.
For each of the four violent crime types tracked in the survey – simple assault, aggravated assault, robbery
and rape/sexual assault – there was no statistically significant increase either in 2020 or 2021.
The National Crime Victimization Survey is fielded each year among approximately 240,000 Americans ages
12 and older and asks them to describe any recent experiences they have had with crime. The survey counts
threatened, attempted and completed crimes, whether or not they were reported to police. Notably, it
does not track the most serious form of violent crime, murder, because it is based on interviews with surviving
crime victims.
TEXT 2:
While the total U.S. violent crime rate does not
appear to have increased recently, the most
serious form of violent crime – murder – has
risen significantly during the pandemic
Both the FBI and the Centers for Disease Control
and Prevention (CDC) reported a roughly 30%
increase in the U.S. murder rate between 2019 and
2020, marking one of the largest year-over-year
increases ever recorded. The FBI’s latest data, as
well as provisional data from the CDC, suggest that
murders continued to rise in 2021.
