A public aquarium has plans to put a freshwater display next to a Dead Sea exhibit in order to showcase the stark difference between the two environments (lots of life vs. no life and lots of salt!). A square access gate exists between the two exhibits. Before filling the two tanks, maintenance wants to ensure that the lock, located at the bottom of the gate, is strong enough to hold the gate shut. Patm a.) What is the magnitude of the force that the lock must be able to support? b.) Should the lock be installed on the left side (to prevent the gate from opening toward the freshwater tank) or to the right side (to prevent the gate from opening toward the Dead Sea Tank)? + h HOT A = bh I bh 12 0 gate fresh water exhibit p=1025 kg/m 3 m 4 m Dead Sea exhibit p=1236 kg/m
