- QUESTIONS: 1-Answer the below questions as "true(T)"or "false (F)^ast and mention with one sentence why and for 1(a) fill right words in the empty spaces. [Each is 3 points. Total 30 points) (a) What two properties of lightweight sandwich materials possess to be used in aircraft structures? Good __ __ and good (b) The equations of compatibility of strains derived such as (partial ^2epsilon _(xx))/(partial y^2)+(partial ^2xyy)/(partial x^2)=(partial ^2Yxy)/(partial xpartial y) be applied. Following a similar procedure with Ea and a and then with Err and Ea These are the only three strain compatibility equation. __ (c) The Green shearing strains have twice the value of the corresponding engineering shearing strains. __ (d) The strain -displacement equations are a necessary part displacement formulation. __ (e) Superposition principle states that, for linearly elastic direction bear a fixed ratio to the strains in the other two orthogonal directions. __ (f) The product of the ultimate load factor to develop ultimate loads whose corresponding stresses are required to be less than the limit stresses. __ (g) The equations of equilibrium, which are derived for the shape, do not apply to a material undergoing plastic deformations. __ (h) Equilibrium equations are always sufficient to structural body in a state of plane stress but are not always sufficient to determine all the displacements in that same structure. __

- lengthwise-slit annular tube and a closed annular tube have the same mean di diameter D If center of thickness to center of thickness) and same tube thickness t, where D=18t tubes are subjected to the same torque , what then is the ratio of the angles sections M_(t)=2Aq For open thin walled sections J=(1)/(3)bt^3 and tau _(max)=(M_(t)t)/(I) if b/tgeqslant 10
- Find I_(0) in Fig. 10.8 using mesh-analysis. Answer: 5.969/55.45 A
- 2. An aluminum alloy is required to withstand at least 10^7 stress cycles. The results of the tests show that when the range of stress changes is equal to 114.3 or 161.5 MPa.the part will break after 10^8 cycles or 10^5 cycles, respectively. If the fatigue behavior of this alloy can be expressed by the following equation, C=Delta sigma ^20N_(f) Where C=constant and N_(f) is the number of cycles to failure. calculate the appropriate stress __
