6. Assume that your company is operating the identical hydraulic piping system (water) in the Caribbean Islands (24°C) and also in Northern Canada (0 C). Using Poiselle's Law, perform a calculation to estimate the difference in performance, i.e., flow rate, that you should expect. State any assumptions.

Choose correct answer: PMM2 means that a machine follows 2nd law of thermodynamics Select one: True False

Partial Question 9 Which choices are correct explanations about the scanning electron microscope (SEM)? (Select all that apply.) Visible light is the main light source. The microscope can investigate non conductive samples as good as the conductive ones. Samples need to be polished. The condensed beam does not pass through the specimen, but is reflected from a surface of the specimen and was collected to obtain the picture. Useful resolution range is much wider than the optical microscopes.

Which of the following statement is incorrect? Select one: Friction causes objects to move faster Friction is high for dry surface Friction causes objects to slow down Friction force acts opposite to motion

Can someone explain how to read a mm drum dial micrometer and check my work please?

The rate of change of viscosity with temperature is known as viscosity index and high viscosity index means oil will remain the same over a wide range of temperatures, Select one: True False

Q1 / Answer TRUE or FALSE and correct the wrong sentences 1- A simple way to estimate the toughness can be provided by the ductile-tough area. 2- The purity of Alumina is lower than Zirconia 3- Ceramics are inorganic materials mainly consist of hydrocarbons. 4- In the elastic region, the strain is decreased by increasing applied stress. 5- Isotropic material has different I x w xt values.

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…
