13) In the clinical use of ultrasound, a thin layer of gel is put on the skin before the device that emits and receives the reflected sound waves-- the transducer--is placed on the skin This transducer is usually made of a ceramic, barium titanate, which has a density of 5600 kg/m' and through which sound waves travel at 5500 m/s. a) Calculate the values...

Please explain how to do part (b), (c) and (d) only
The PID control architecture might be popular, but that does not mean it can be used for everything. This question explores when the PID controller is (in)sufficient: when it is too much, when it is "goldilocks", and when it is not enough. Consider a plant given by P'(s)-SaAs n increases, so does the order of the system. (sta)" Let's consider three orders and how PID controller design works for...

Part B (Based off week 11 workshop content) An engineering company has ordered steel to be used for a rail construction project. Before using the steel, they want to test it to ensure the material properties from the supplier are correct. A random sample of the ordered steel is tested for its Yield Strength. The results are shown below. Yield Strength (MPa) 197 203 194 196 196 197 198 205 1. Calculate the sample mean and sample variance by hand,...
