Asign has a mass of 1050 kg, a height h = 1 m, and a width w = 4 m. it is held by a light rod of length 5 m that is perpendicular to a rough wall. a guy wire at 23° to the horizontal holds the sign to the wall. note that the distance from the left edge of the sign to the wall is 1 m.
suppose we rely upon friction between the wall and the rod to hold up the sign (there is no hinge attaching the rod to the wall). what is the smallest value of the coefficient of friction µ such that the sign will remain in place?

Orque can be calculated by multiplying the force (n) applied at 90∘ to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n⋅m. if the force (at 90∘ to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?
