Each bar chart should show the distribution of energy across the categories as well as the total energy for the initial- red and final- blue state.   The system includes 3 units of heat energy, and 2 units of radiant energy. All of the energy in the final state will be converted into mechanical energy.

1. In the operation of an internal combustion engine, the combustion gases expand in volume to make thepiston move. As this occurs ___________ gas particles move in the same direction as the motion of thepiston.

I need answers for problems 13, 14, and 15 pertaining to the print provided.   NOTE: If you refuse to answers all 3 parts and insist on wasting my question by breaking down 1 simple question into 3 parts, then just leave it for someone else to answer. 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…
