# What sort of force would be needed by the collision of an automobile bumper, located 0.45mabove the ground surface to shear the sign off or break the sign in bending?

Consider a typical way sign on a highway
that is 3mwide and 1mtall. It is placed on two aluminum
columns that are 2.5mto the bottom of the sign, and which
extend all the way to the top. These columns are built from box beams 150mmon a side. Wind load on the sign.0/msohtmlclip1/01/clip_image006.gif”>is , whereCd= 1.28 , rho= 1.2kg/m3

wind speed. All quantities are in metric units. Determine the wall thickness
needed to just resist a wind speed of 50m/s.
Consider only bending, and use pure aluminum as the material under
consideration. What sort of force would be needed by the collision of an
