The floor framing in an office building consists of reinforced concrete beams 18 in. × 24 in. deep that support precast concrete planks on a 3-in. ledge similar to that shown in Figure. The clear span of the beam is 27 ft between columns. The planks are 10-in. deep with 2-in. topping and supports stud wall partitions that weigh 10 psf and mechanical/electrical equipment that weigh 5 psf. The weight of the precast planks is 70 psf. The centerline to centerline span of the planks is 30 ft on the left-hand side of the beam and 10 ft on the right-hand side of the beam. The live load on the 30-ft span is 50 psf while the live load on the 10-ft corridor span is 100 psf. Design the beam for torsion and shear assuming normal weight concrete (i.e., λ = 1.0), f′ c = 4000 psi and fy = 60,000 psi. Assume the beam has already been designed for bending.

A 1.0 litre bottle of water weighs 9.79 N at sea level. If the bottle was taken to the top of Mt Everest (8848 m above sea level), how much would it weight there? Take g at sea level to be 9.81 m/s2 and the radius of the Earth to be 6371 km.
A six-cylinder four-stroke engine operating at 3000 rpm produces 200 kW of total brake power. If the cylinder displacement is 1 L, determine (a) the net work output in kJ per cylinder per cycle, (b) the MEP and (c) the fuel consumption rate in kg/h. ..
Explain what is meant by ‘inversion of control' in application frameworks. Explain why this approach could cause problems if you integrated two separate systems that were originally created using the same application framework.
The extrusion ratio, die geometry, extrusion speed, and billet temperature all affect the extrusion pressure. Explain why.
