Why is the polygon method reasonable graphical technique?
The polygon method is most suitable graphical technique for analyzing concurrent forces because it allows for the graphical addition of multiple vectors without the need any complex calculations. This method is particularly useful when dealing with systems of forces acting at a single point or in a plane. By using the polygon method, can visually determine the resultant of multiple forces, which simplifies the analysis and helps in understanding the overall effect of the forces on a system
Whats the definition of a irregular polygon?
The definition of a irregular polygon is any polygon that is not a regular polygon.
What does a polygon have to have to be a polygon?
A polygon is a Two dimensional figure that is closed.
Do a polygon have to be closed for it to be a polygon?
Yes. A polygon is a closed figure.
What is the sum of the interior angle measured by a 20-sided polygon?
162o. Method 1: Sum of interior angles of n-sided polygon = (2n - 4) right angles. In this case n = 20 so total of interior angles is 36 x 90o. Assuming polygon is regular then each interior angle is (36 x 90) divided by 20 = 3240/20 = 162. Method 2: Exterior angles of regular n-sided polygon = 360/n which in this case = 360/20 =18. Straight line is 180o so interior angle = (180 - exterior angle) = 180 - 18 = 162.
