Question
where d is the force's moment arm. The moment arm is the perpendicular distance from the axis at point O to the force's line of action. 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. (Part A 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 = 213 N . m, what is the maximum height d1 that the stool can have if the magnitudes of the two forces are F1 = 200 N and F2 = 975 N? Assume that moments acting counterclockwise about point A are positive whereas moments acting clockwise about A are negative. Express your answer numerically in meters to three significant figures. This part will be visible after you complete previous part(s). This part will be visible after you complete previous part(s).Explanation / Answer
Moment = Force * Perpendicular distance Moment due to F2 = 0 as distance = 0 Moment due to F1 = 200*d1 Maximum sustainable moment = 213 Nm 213 = 200*d1 d1 = 1.065 m
