For the composite cylinder shown in Fig. 5.25, what thick-ness of brass is required to cause the cylinder to float in the position shown in carbon tetrachloride at 25°C?

As shown in Figure 2.1, liquid of density pis trapped by a gate ABC of unit width into the plane of the page. The gate is hinged at C, and consists of a vertical section AB of length H and an inclined section BC also of length H inclined at an angle with respect to the horizontal. Obtain an expression for the force P required to hold the gate in position. Neglect the weight of the gate and friction in the hinge.
