3. A body is subjected to a direct tensile stress (?) in one plane. The shear stress is maximum at a section inclined at __________ to the normal of the section.
4. A simply supported beam 'A' of length l, breadth b and depth d carries a central point load W. Another bream 'B' has the same length and breadth but its depth is doubled. The deflection of beam 'B' will be double as compared to beam 'A'.
7. Two solid shafts 'A' and 'B' are made of the same material. The shaft 'A' is of 50 mm diameter and shaft 'B' is of 100 mm diameter. The strength of shaft 'B' is __________ as that of shaft A.
8. When the retained material is subjected to some superimposed or surcharged load, the total horizontal pressure due to surcharged load is (where p = Intensity of the supercharged load)
