Both of the tension and compression forces are exerted on the concrete specimen when investigating the flexural strength. However, the specimen fails due to the flexural forces. * True False Other:

3. The block is subjected to a triaxial loading as shown. If v = 0.30 and E = 29 x 106 psi, determine the following: a) the single uniformly distributed load (in kips) in the x-direction that would produce and the same deformation in the y-direction as the original loading b) the single uniformly distributed load (in kips) that must be added in the load which exists in the x-direction to produce no deformation in the z-direction. HINT: No deformation in the z-direction means there is no strain in that specific direction but is still subjected to a particular stress. With that, correlating different strains by Poisson's ratio may not be applicable in this part. Use 6 decimal places for the solved values of strain and 3 decimal places in other values. y 60 kips 48 kips 54 kips 2" 54 kips 48 kips x. 3" 60 kips 4"
The point loads are placed at the fixed positions shown in the figure and they are live loads. A k a b a b dn = 1₂ Icr= M B 7 Ast Stress profile (concrete) Cross section before cracking Aso Cross section Asc Ast N.A. Q2) Now, the live load increases gradually and the moment at the critical section just exceeds the cracking moment (Mcr), but the compressive section of the concrete is still under the linear elastic region. Please be reminded that in the flexural design, the crack of the concrete section starts where the tensile stress reaches the tensile strength. It is assumed that the cracks then propagate rapidly up to the entire tension section (up to the neutral axis) and this cracked concrete section cannot resist the tension. It should be noted that in reality, concrete sections between the primary cracks can still resist some tensile stresses as shown in the figure, which should be considered in the displacement design. However, in flexure design, we design the critical section…
