Question

Problem 1: An aquarium is building a tank for dolphins. The tank is to hold sea water at 36° F and contains a triangular access plate for maintenance. If the plate is held in place by 6 bolts, what is the force required in each bolt? If a 10 cm hole forms in the center of the access plate and a worker places their hand over the hole, what is the force on their hand? 5 m 1.8 m T1 m 1 m
