So you can tell if the motor is turning (running) just by looking.

To avoid slugging nozzles and blades inside the turbine with condensate on start-up; this can break these components from impact. The blades were designed to handle steam, not water.

With the above mentioned answer, it is pretty much correct except for the twin engine aircraft. For the twin engine aircraft, the critical engine is the one that produces a thrust line closest to the fuselage. Example: if the twin engine aircraft is equipped with 2X engines which have the propeller rotating in a clockwise direction, then the left engine will be the critical engine. This is because the down going blade on the left engine will produce a line of thrust closest to the fuselage compared to the right engine's propeller. So it is safe to say that if the left engine fails, the aircraft will be harder to control because the thrust line produced by the live engine on the right side has a longer arm from the fuselage causing a higher moment wanting to yaw and roll the aircraft to the left which is harder to control compared to if the right engine fails, such as the Piper Twin Comanche aircraft. However, if the twin engine aircraft is equipped with counter rotating propellers, meaning, the left engine prop rotating clockwise and the right engine propeller rotating counter clockwise, then there is no critical engine, because both down going blades of the propeller produces a thrust line both equal in distance from the center of the fuselage.
An inline engine has all the cylinders in a straight line. A V engine has 3 on one side and 3 on the other with the cylinder block actually in a V shape. The V shape was originally used to save space because a V engine is a little shorter than an inline engine. In the old days it was believed that an inline engine would produce more torque and a V engine would produce better horsepower and higher RPM's because of better balance. In today's world with computerized manufacturing we are back to more about space than anything.
A spiral is a line, hence its area is zero. For the area of a spiral line of given width, you've moved away from simple math.
a spiral or a straight line
Select any point in the plane as the origin. From the origin, draw a line of unit length. At its end draw a perpendicular line, also of unit length. This is the first line of the spiral. Join the end of this second line to the origin - this will be a line of length sqrt(2). At the end of this line draw a perpendicular line of unit length. This is the second line of the spiral. Join the end of this new line to the origin - this will be a line of length sqrt(3). At the end of this line draw a perpendicular line of unit length. This is the next line of the spiral. Continue until you have had enough! Or, follow the link.

A spiral line in art refers to a curved line that gradually moves away from or towards a central point, creating a spiral shape. This design element can evoke a sense of movement, growth, or dynamism within a composition. Artists often use spiral lines to guide the viewer's eye or to symbolize concepts such as evolution, continuity, or the passage of time. Famous examples include the use of spiral forms in works by artists like Vincent van Gogh and in the architecture of structures like the Fibonacci spiral.
it is used balance axial thrust on turbine rotor due to admitting of high pressure steam in to turbine. it basic purpose is to save thrust bearing.
A turtle that has a red line on its neck is probably a painted turtle. Painted turtles are the most common turtle in North America.
Great question-- Birds generally stay away from areas where there is an fake (or REAL) owl, but they also will NOT nest or even land around a fake rubber or wood snake. In fact a painted wiggly line will panic them. That's why jets have a wiggly or spiral line painted on their inlet hubs. You can also try various products from bird-x.com . They have decoys, spikes, sonic and ultra sonic sound machines that work really well.
