Question 2369
Among the following, which one is categorically NOT a component of Gross Domestic Product (GDP) calculated by the expenditure approach?
Correct Answer Logic:
The expenditure approach to GDP is: \(\text{GDP} = C + I + G + (X - M)\), where \(C\) = household consumption, \(I\) = gross private investment, \(G\) = government purchases, and \((X-M)\) = net exports. The rate of unemployment is a labour market indicator and is not a component of GDP. It may be correlated with GDP (via Okun's Law) but is not included in its calculation.

Correct Answer Logic:
Per ACI 318 Section 9.8.1, for joist (ribbed) and waffle slab systems, ribs shall not be less than 100 mm wide, and the overall depth of ribs shall not exceed 3.5 times the minimum rib width. Therefore rib width โฅ 100 mm and depth โค 3.5 ร 100 mm = 350 mm. The clear spacing between ribs shall not exceed 750 mm. These dimensional limits ensure proper concrete placement, adequate cover, and structural integrity of the one-way or two-way ribbed slab system.

Correct Answer Logic:
