A heavy car plunges into a lake during an accident and lands at the bottom of the lake on its wheels. The door is 1.2 m high and 1 m wide, and the top edge of the door is 8.8 m below the free surface of the water. Determine the hydrostatic force on the door and its location from the free surface. 8.8m Z LakeA gate AB 4 ft long and 2 ft wide is held in position shown due to the spring whose constant is 96.0 Ibf/in. The spring is located compressed 1.5 ft in such a way as to keep the gate in equilibrium. Assume that on the gate (which moves through a circular sector BD as shown in Fig. figure), the force due to the spring is always horizontal. Determine the height d of the water.
- A person wearing long snowshoes can walk across a blanket of freshly fallen snow without sinking far into the snow because (p.s. Google snowshoe if you don't know how one looks like) snowshoes cover a larger area than a foot and so the pressure is reduced. the snowshoes reduce the force of the person on the snow. the large area of the snowshoe concentrates the force of the person to a point smaller than the foot. snowshoes push less dense snow out of the way so the person stands on more solid ice below... hinge 1.2m water 2.4m 1.8m A rectangular gate AB shown is hinged at "A" and rests on a smooth floor at "B".
