Consider the suspended sign that is shown below. The sign is 3 mm thick and is made of aluminum. (The density of aluminum is 2,740 kg/m.) 4 m Sign 1 m 2 m 9 m O What is the volume (in m ) of the sign? m3 What is the acceleration due to gravity (in m/s2)? m/s2What is the weight (in N) of the sign? N What is the perpendicular distance (in m) between the line of action of the force and the point O? m Determine the moment created by the weight of the suspended sign about O. (Enter the magnitude in N . m.) N . m Is the direction of the moment clockwise or counterclockwise? O clockwise O counterclockwise
