I Review Part A Learning Goal: To understand the concept of moment of a force and how to calculate it using a scalar formulation. A stool at a restaurant is anchored to the floor. When a customer is in the process of sitting down, a horizontal force with magnitude F is exerted at the top of the stool support as shown in the figure. (Figure 1) When the customer is seated, a vertical force with magnitude F, is exerted on the stool support. If the maximum moment magnitude that the stool support can sustain about point A is MA = 230 N - m , what is the maximum height d that the stool can have if the magnitudes of the two forces are F = 160 N and F, = 690 N ? Assume that moments acting counterclockwise about point A are positive whereas moments acting clockwise about A are negative.
