3. The underwater gate is holding water from entering inside the channel with atmospheric pressure inside, so assume it is negligible. Outside is a fresh water with the density of 1000 kg/m’. At p.C is a pin holding the gate (two reactions!). There is a lock at p.A with horizontal reaction. The length of a gate is 8m (perpendicular to you). Determine: .1 The pressure on the BC and AB 3.2 Reactions at p.C and p.A. 3.3 Will the bolt in the pin C will sustain the fluid if the max load is 1,000 N? Note: The max load is a resultant force from both x- and y- reactions. 1.5 m 1.25 m 2 m
