The discussion revolves around calculating the shortest ladder needed to reach over a fence between two perpendicular streets. The problem specifies a beam length of 62.50 m and a street width of 32 m. The solution proposed is 13.5 m, based on the relationship Si² - s² = 62.50. Participants are encouraged to refer to a similar problem linked in the discussion for further insights. The conversation emphasizes understanding the geometric relationships involved in the problem.

342) a beam of 62, 50.m passes horizontally by 1 street 32 m wide to other street perpendlcular which is the width of the second street
?.
Answer 13.5 m

the omly thing is since the 2 streets are perpendicular Si2-s2 =62,50

Thread 'Problem with calculating projections of curl using rotation of contour'

Hello! I tried to calculate projections of curl using rotation of coordinate system but I encountered with following problem. Given: ##rot_xA=\frac{\partial A_z}{\partial y}-\frac{\partial A_y}{\partial z}=0## ##rot_yA=\frac{\partial A_x}{\partial z}-\frac{\partial A_z}{\partial x}=1## ##rot_zA=\frac{\partial A_y}{\partial x}-\frac{\partial A_x}{\partial y}=0## I rotated ##yz##-plane of this coordinate system by an angle ##45## degrees about ##x##-axis and used rotation matrix to...
