For deflection calculations of reinforced concrete beams, which of the following statements is true: The most common factored load combination to be used for deflection calculations is 1.2 for dead loads and 1.6 for live loads. Camber must be introduced in all beam designs to compensate for the initial beam deflections due to dead loads In most beam designs, the dead load deflections are more important than the live load deflections Deflections of reinforced concrete beams need to be calculated based on a varying effective moment of Inertia corresponding to the level of loading due to the different amounts of cracking
