Question 5 Answer the following questions concisely (no more than half a page per question): a What do you understand by strength, stiffness and stability in the Mechanics of Solids context? b Identify, sketch and explain how to calculate all possible failure modes of a bicycle chain (for the link plates and the pin). c What is/are the difference(s) between von Mises (Maximum Distortion Energy) and Tresca (Maximum Shear Stress) failure criteria? d Give a structural engineering explanation to the placement of pinnacle statues on top of flying buttress columns of Gothic Cathedrals. e Give a structural engineering explanation to the structural failure of the "grabbing" arms of the capture vehicle used to raise the Russian submarine K- 129.

Read and Solve carefully please Write clearly and Box the Final answer Express your answer to 3 Significant figures and include appropriate units.

Fatigue data of steel is showed in the following stress-cycle curve.Write down the values of steel endurance limit and steel fatigue strength at 10^5 cycles in the spaces provided below.Steel Endurance Limit: _____ ksiteel Fatigue Strength at 10^5 cycles: _____ ksi

A gauge # 10 HSLA steel for an automotive application has a Young’s modulus of 200 GPa, a yield strength of 370 MPa and a ultimate tensile strength of 440 MPa. What is the punch force needed to punch a square hole with a side length of 20 mm on this HSLA steel? Show your work.

Stuck need help! Problem is attached. please view attachment before answering.  Really struggling with this concept. Please show all work so I can better understand ! Thank you so much.

Note: this is not assignment question and not a graded question

these are shot questions please answer the all questions it's important for me

The answer is one of the options below please solve carefully and circle the correct option Please write clear .

Select All the correct statements from below.  a. If the averaged distance between partial dislocations for material A observed under TEM is smaller than material B, the estimated stacking fault energy of material A is lower than material B. b. K_IC is a material property that doesn't change with testing conditions c. The main difference between high cycle fatigue and low cycle fatigue is the difference in the number of cycles to failure d. A negative R value in fatigue test indicate the minimum stress is compressive in nature
