The structure shown in below figure is stable, if

A solid cube is subjected to equal normal forces on all its faces. The volumetric strain will be x-times the linear strain in any of the three axes when

The nature of the stress in horizontal members of the truss shown in below figure may be

If the normal cross-section A of a member is subjected to tensile force P, the resulting normal stress in an oblique plane inclined at angle θ to transverse plane will be

A simply supported wooden beam 150 cm long and having a cross section 16 cm x 24 cm carries a concentrated load, at the centre. If the permissible stress ft = 75 kg/cm² and f_s = 10 kg/cm² the safe load is
