A crate weighs 585 lb and is hung by three ropes attached to a steel ring at A such that the top surface is parallel to the xy plane. Point A is located at a height of h = 31 in above the top of the crate directly over the geometric center of the top surface. Use the dimensions given in the table below to determine the tension in each of the three ropes. 2013 Michael Swanbom cc 040 BY NC SA Z C b x B у a D Values for dimensions on the figure are given in the following table. Note the figure may not be to scale. Variable Value a 48 in b 29 in C 13.2 in The tension in rope AB is lb The tension in rope AC is lb The tension in rope AD is lb

The following diagram shows a partial floor framing plan of an elevated walkway building connecting an airport terminal building to the adjacent garage. The concrete floor is not post- tensioned. Material properties are: - Concrete weight: wt = 150 pcf - Concrete compressive strength: f'c = 4000 psi - Steel tensile strength: fy = 60 ksi - Stirrup consists of #4 bar - Framing members are not exposed to weather or in contact with soil. Per the ACI, what is the minimum slab depth? Consider both the interior slab and the cantilevered slab at the edge of the building. 30-0¹ B4 B4 B4 83 Column 52 SI 30-0 -Sab Mark Dean- B4 B4 B4 83 B 30-0¹ BI B2 B2 BI -Girder 12 A 1 3-4 Ei 13:4 05 40-0 to 2
