As you probably know that the Angle is the measure of rotations taken by a ray around its initial point. But, have you ever thought what could be the practical applications of Angles in real life ?
Position, direction, precision, and optimization are some reasons why people use angles in their daily life. In this post you are going to learn about the 5 best practical real life applications of Angles. So let’s dig in.
1.) At Street Intersections –
Street intersections are made at angles as close as possible to 90°, if not greater, so that visibility is easier when turning. It is beneficial for city planners to create additional turns so that there are larger turning angles for safer traffic.For example, if a car has to make a sharp 60° turn onto traffic, it
would probably be more likely to get into an accident because the turn is
difficult. If you find a non-perpendicular four-way intersection with a
stoplight, it is likely to have a “No Turn on Red” sign for those drivers who
would be at an obtuse angle. It would be easier for the driver if the road were
constructed so that an additional intersection is added so the car can turn
once at 150° and again at 90°.
2.) In The Parking Spaces –
The use of angles in the design of parking spaces affects how many cars
can park in a lot. Most parking arrangements involve spaces that are
perpendicular or slightly angled to the curb. An advantage to using
obtuse-angled spaces is that it is easier to turn a car at an obtuse angle than
at a right angle, so there may be less accidents in a lot with angled spaces.
An advantage to using right-angled spaces is the opportunity to fit more cars
in the parking lot.
3.) In
Airplane and Ship Navigations –
Airplane pilots, military-orienteering specialists, and ship-navigation
crews are responsible for using angles to move efficiently towards a
destination. After accounting for wind and current speed, navigation teams will
determine an angle to direct their course of movement. For example, suppose a
ship is 3 miles from shore and is docking at a port that is 6 miles away, with
minimal current affecting he path of the boat. The captain will request the
boat to be moved 60° West of North, or 30° North of West. This direction is equivalent
to the angle that is formed between the path of the boat and the northern or
westward direction. The captain can also simply ask to move the boat 60°, because
it is assumed that navigation direction is counter-clockwise from the North
position.
4.) In Sailboats Sailing –
Sailboats cannot steer directly into the wind, because they would be
pushed backwards. In order to sail against the wind, sailors need to tilt their
boat at an angle, ideally 45°, so that the wind catches the sail. If the boat
pushes off course, it will need to change direction again so that it moves
perpendicular to its path in the opposite direction. Sailors call this tacking.
This action ensures that the boat continues to maintain a 45° angle with the
wind. This zigzag pattern enables the boat to reach its finishing point while
constantly sailing into the wind.
5.) In Sports & Games –
Athletes who try to throw or hit balls certain distances, such as baseballs, basketballs, footballs, and golf balls, use angles strategically. If they want to hit a ball short and high, they will use an angle close to 90°. In order to hit a low-flying line drive, they will use an angle close to 0°. When a golfer tees off or a football kicker aims for a long field goal, he or she should strike the ball at a 45° angle in order to obtain maximum distance. Frogs know this angle: push-off angle for a frog hop has been measured to be close to 45°.
