Question

3. Water level in a flush tank is controlled by the mechanism shown in the figure associated with problem 3.50 in Katz' textbook. The condition shown, represents the 'tank full' condition and the water supply valve is closed. Assuming a negligible mass for the half sunken ball (of radius R = 0.10 m), calculate the vertical force on the valve at point B. (note that the arm is hinged at point A and $l_1$ = 0.12m and $l_2$ = 0.040m).

Step 1

Since the ball is half submerged in water, it experiences a buoyant force equal to the weight of the water displaced by the submerged portion of the ball. The buoyant force can be calculated using the formula: Buoyant force = density of water * volume of Show more…
