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 F1 is exerted at the top of the stool support as shown in the figure. When the customer is seated, a vertical force with magnitude F2 is exerted on the stool support. If the maximum moment magnitude that the stool support can sustain about point A is MA = 195lb-ft , what is the maximum height d1 that the stool can have if the magnitudes of the two forces are F1 = 70.0lb and F2 = 115lb? Assume that moments acting counterclockwise about point A are positive whereas moments acting clockwise about A are negative.
