Problem 11.9 The cube of material shown in Problem 11.8 (reproduced below) is subjected to a pure shear stress T. If the normal stress on the plane P is -20 ksi, what is t?

I need answers to questions 1, 2, and 3 pertaining to the print provided. Note: A tutor keeps putting 1 question into 3 parts and wasted so many of my questions. Never had a issue before until now, please allow a different tutor to answer because I was told I am allowed 3 of these questions.

I need parts 4, 5, and 6 answered pertaining to the print provided.

Last person got every single question wrong and didn't include units. Please help.

The class I'm taking is physics for scientists and engineers! **** I need help with part  D only*****  Can you please write out the solution and not type out the solution? I had to reask this question because the last tutor typed out the solution and it was very hard for me to follow . Please and thank you for the special request. I have attached the problem. Please view attachment before answering. Thank you!

Question 2 You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial weight bearing activities. Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the yield stress for the…
