Consider a bar of diameter $$'D'$$ embedded in a large concrete block as shown in the adjoining figure, with a pull out force $$P$$ being applied. Let $${\sigma _b}$$ and $${\sigma _{st}},$$ be the bond strength (between the bar and concrete) and the tensile strength of the bar, respectively. If the block is held in position and it is assumed that the material of the block does not fail, which of the following options represents the maximum value of $$P?$$ A
Maximum of $$\left( {{\pi \over 4}{D^2}{\sigma _b}} \right)$$ and $$\left( {\pi \,DL\,{\sigma _{st}}} \right)$$
B
Maximum of $$\left( {{\pi \over 4}{D^2}\,{\sigma _{st}}} \right)$$ and $$\left( {\pi \,DL\,{\sigma _{b}}} \right)$$
C
Maximum of $$\left( {{\pi \over 4}{D^2}\,{\sigma _{st}}} \right)$$ and $$\left( {\pi \,DL\,{\sigma _{b}}} \right)$$
D
Maximum of $$\left( {{\pi \over 4}{D^2}{\sigma _b}} \right)$$ and $$\left( {\pi \,DL\,{\sigma _{st}}} \right)$$

Consider the following two statements related to reinforced concrete design, and identify whether they are TRUE/FALSE:

$${\rm I}.$$ Curtailment of bars in the flexural tension zone in beams reduces the shear strength at the cut-off locations
$${\rm II}.$$ When a rectangular column section is subject to biaxially eccentric compression, the neutral axis will be parallel to the resultant axis of bending.

A
Both statements $${\rm I}$$ and $${\rm II}$$ are TRUE.
B
Statement $${\rm I}$$ is TRUE, and $${\rm II}$$ is FALSE
C
Statement $${\rm I}$$ is FALSE, and statement $${\rm II}$$ is TRUE
D
Both Statements $${\rm I}$$ and $${\rm II}$$ are FALSE
