A shed is shown below. It is 10 feet wide and 20 feet long and has a slanted flat roof (i.e., a plane roof) that is 12 feet high at one corner and 10 feet high at the two corners next to that one. Z (a) [5] Three corners of the roof are given by the points (0, 0, 12), (10, 0, 10), and (0, 20, 10). 12 Find the vector vị from (0, 0, 12) to (10, 0, 10)...

The truss shown in the figure below is one of several roof trusses spaced at 20 feet apart. Purlins are located at the joints. The weight of the roofing material is 5 psf, and the snow load is 15 psf of horizontal projection of the roof surface. The self-weight of the truss (including purlins) is estimated to be 10 psf of horizontal projection of the roof surface. Use LRFD and design the lightest square HSS for the most critical top...
The truss shown in the figure below is one of several roof trusses spaced 15.0* at 20 feet apart. Purlins are located at the joints.
