Math Problem Statement
A uniform square sign with sides of length 0.68 m is fixed at its corner points A and B to a wall. The sign is also supported by a wire CD. The tension in the wire is 54 N at an angle of 35° to side BC. Calculate the vertical component of the tension in the wire and explain why the force on the sign at B does not have a moment about point A.
