Four identical rods are connected in series and hanging from the ceiling (as shown in the figure). In equilibrium, what is Tan A/Tan B
It is simply a half section of a Octagon, therefore the angle subtended at each section will be equal to 45 degrees. so the angle A=(180-45)/2 =67.5 degrees similarly by observation B=(67.5-45)=22.5 degrees. Now Tan(A)/Tan(B) =Tan(67.5)/Tan(22.5) = 2.**********.
You are in a one-story house, and everything is blue. The floors, the ceiling, the walls, the tables, the chairs, everything is blue! What color are the stairs?
