A shopper holds a bag of shopping with their arm hanging straight down. They then hold the same bag with their arm straight out in front of them. Which statement about the moment of the weight of the bag about the shoulder is correct?
The moment is larger with the arm held out, because the perpendicular distance is larger
The moment is larger with the arm hanging down, because the weight acts straight downwards
The moment is the same in both positions, because the weight of the bag is unchanged
The moment is zero with the arm held out, because the bag is not moving upwards
