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

The flow of water from a container is controlled by a 5-ft-wide L-shaped gate hinged at point A, as shown in the figure. If it is desired that the gate open when the height of the water is 10 ft, determine the weight W of the counterweight to achieve this. Take d= 5 ft and H = 16 ft. Give your answer in lb and without decimals.
