34.
The cylinder strength of the concrete is less than the cube strength because of
the difference in the shape of the cross section of the specimens
the difference in the slendeness ratio of the specimens
the friction between the concrete specimens and the steel plate of the testing machine
the cubes are tested without capping but the cylinders are tested with capping

According to me here we can apply the concept of Section of moduls (Z). Z increase than strength increase &in cylinder z is less compare to cube.

C is the correct answer in this question because the restraining effect due to friction.

The correct option is C.

The middle portion of the cylinder has the negligible effect of friction. Cube has a uniform effect throughout.

The correct answer is A, friction is present in both the cases but in-cylinder its impact is negligible as compared to cube because of its larger cross-section area i.e. shape is different of cross-section.

Option B is correct. When Effective length to least lateral dimension is considered here value of lamda is more for cylindrical section and hence more chance of failure.
