1. Let's clarify the terms: "moment of vertical" and "moment of horizontal" likely refer to moments about vertical and horizontal axes, commonly used in physics and engineering. 2. The moment (torque) about an axis is calculated as the force multiplied by the perpendicular distance from the axis to the line of action of the force. 3. For a vertical axis, the moment is calculated using the horizontal distance from the force to the axis: $$M_{vertical} = F \times d_{horizontal}$$ 4. For a horizontal axis, the moment is calculated using the vertical distance from the force to the axis: $$M_{horizontal} = F \times d_{vertical}$$ 5. So, yes, it is correct to refer to moments about vertical and horizontal axes, but you must use the perpendicular distance to the respective axis in the calculation. 6. Always ensure you identify the correct axis and measure the perpendicular distance accordingly to compute the moment accurately.
