The following figure shows the arrangement of formwork for casting a cantilever $\mathrm{RC}$ beam.



The correct sequence of removing the Shores/Props is

  1. $\mathrm{S} 1 \rightarrow \mathrm{S} 2 \rightarrow \mathrm{S} 3 \rightarrow \mathrm{S} 4 \rightarrow \mathrm{S} 5$
  2. $\mathrm{S} 5 \rightarrow \mathrm{S} 4 \rightarrow \mathrm{S} 3 \rightarrow \mathrm{S} 2 \rightarrow \mathrm{S} 1$
  3. $\mathrm{S} 3 \rightarrow \mathrm{S} 2 \rightarrow \mathrm{S} 4 \rightarrow \mathrm{S} 1 \rightarrow \mathrm{S} 5$
  4. $\mathrm{S} 3 \rightarrow \mathrm{S} 4 \rightarrow \mathrm{S} 2 \rightarrow \mathrm{S} 5 \rightarrow \mathrm{S} 1$
