|Length of crank bar on one side= d/sin@ - d/tan@
= d/sin45° - d/tan45°
Therefor total length of cranked bar on both sides = (L+2x0.42d).

|If bar cranked at 30 then extra length will be 2*0.27d.|

|Here it is not mentioned that crank is on both sides. So the answer must be A.
Crank is provided to resist negative BM.
Crank is provided to resist shear force.

|Option A is correct because it is not mentioned about the crank on both sides.|
