A puck weighs 6 lb and rests on the center of the frictionless surface of the ramp supported in equilibrium by ropes AC and BC. Determine the normal force the ramp exerts on the puck as well as the tension in each of the two ropes. X B A d 80 g b Values for dimensions on the figure are given in the following table. Note the figure may not be to scale. Variable Value a 50.0 in b 60.0 in C 30.0 in d 60.0 in e 60.0 in f 12.0 in g 72.0 in The normal force acting on the puck is pounds The tension in rope AC is The tension in rope BC is pounds pounds

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
