A cantilever pin-jointed truss carries one load P at the point Z as shown in the given figure. The hinges in the vertical wall are at A and D. The truss has only three horizontal members AC, CG and GZ. The nature of force in member AB
A saturated stiff clay has unit weight 2 gm/cm3 and unconfined compressive strength 2 kg/cm2. The depth of tension crack that would develop in this clay is
Consider the following statements : 1. In a member subjected to uniaxial tensile force the maximum normal stress is the external load divided by the maximum cross-sectional area. 2. When the structural member is subjected to uniaxial loading, the shear stress is zero on a plane where the normal stress is maximum. 3. In a member subjected to uniaxial loading, the normal stress on the planes of maximum shear stress is less than the maximum. Of these statements :
