Question:

In Prob. 3.56, determine the perpendicular distance between member GH and edge AD of the walkway. Problem 3.56: The 2.4-m-wide portion ABCD of an inclined, cantilevered walkway is partially supported by members EF and GH. Knowing that the compressive force exerted by member GH on the walkway at H is 21.3 kN, determine the moment of that force about edge AD of the walkway.
