Figure Q4 (a) shows an L-bracket ABC with diameter d which lies in the horizontal plane. It is made from a material with elastic and shear moduli E and G, respectively. If a vertical load P is applied at end C, determine the total strain energy that is stored in the whole structure. Express your answer in terms of P, E, G, d and L. Neglect the strain energy due to shear force.
How do I solve this in steps. And what main equations do I use? Thanks
A brittle material made of ASTM grade 30 cast iron has ultimate strength in tension of 31 kpsi and ultimate strength in compression of 109 kpsi and undergoes the following plane of stress state: o, = 20 kpsi and Tyy = 10 kpsi (CW). a) using the 3D Mohr's circle, find all three principal normal stresses. b) using the Brittle-Coulomb-Mohr theory and Modified-Mohr theory, find the factors of safety for the given plane of stress state.
