Is it possible to have a regular polygon with an exterior angle of 45?
Is it possible to have a regular polygon with an exterior angle of 45?
Sum of exterior angle of any polygon is 360o . As each exterior angle is 45o , number of angles or sides of the polygon is 360o45o=8 . Further as each exterior angle is 45o , each interior angle is 180o−45o=135o .
What is the optimal angle to launch a projectile?
45°.
How does angle affect range?
In the nutshell, the range,R, increases with increasing angle of projection for 0° ≤ θ < 45°; the range,R, is maximum when θ = 45°; the range,R, decreases with increasing angle of projection for 45° < θ ≤ 90°. Horizontal range Horizontal range is same for a pair of projection angle.
Why does launch angle affect distance?
Launch angle trajectory comparisons The launch angle determines the maximum height, time in the air, and maximum horizontal distance of the projectile.
Does launch angle affect range?
Launch Angle: The launch angle determines the range and maximum height that an object will experience after being launched. This image shows that path of the same object being launched at the same velocity but different angles.
At what projection angle will the range equal its maximum height?
If the angle of projection is 75.96∘, the maximum height is equal to the horizontal range.
What is a angle of projection?
(i) Angle of projection – It is the angle with the surface with which the projectile is projected. The maximum range angle of the projectile should be 450.
What is the dimensional formula of angle of projection?
Angle is defined as the ratio of length of arc to radius. Substituting in the above formula we get, Dimensional formula of Angle = M0L0T0. We can also say Angle is dimensionless quantity.
Why don’t we use 2nd and 4th angle projection?
Overlapping projection views create confusion in the drawing. Therefore the 2nd angle projection system is not used to draw engineering drawings. Similarly when the object is placed in the 4th quadrant both top and front view will overlap. Therefore fourth angle projection is also not used.
Why do we use 1st angle projection?
So, just for the simplicity of drawing the orthographic views, we prefer first angle projection. In other words, Orthographic projection is a way of drawing a 3D object from different directions. The way in which we position these three views, differentiates third angle projection from first angle projection.
