a. Find the poles of the closed loop transfer function for different values of K. How does the poles move as you change K?
b. Find the step response for different values of K and plot in MATLAB. What can you observe?
a box shaped barge 37m long, 6.4 m beam, floats at an even keel draught of 2.5 m in water density 1.025 kg/m3. If a mass is added and the vessel moves into water density 1000 kg/m3, determine the magnitude of this mass if the fore end and aft end draughts are 2.4m and 3.8m respectively.

- I submitted the below question and received the answer i copied into this question as well. Im unsure if it is correct, so looking for a checkover. i am stuck on the part tan-1 (0.05) = 0.04996 radians. Just unsure where the value for the radians came from. Just need to know how they got that answer and how it is correct before moving on to the next part. If any of the below information is wrong, please feel free to give me a new answer or an entire new explanation. An Inclining experiment done on a ship thats 6500 t, a mass of 30t was moved 6.0 m transvesly causing a 30 cm deflection in a 6m pendulum, calculate the transverse meta centre height. Here is the step-by-step explanation: Given: Displacement of the ship (W) = 6500 tonnes = 6500×1000=6,500,000kg Mass moved transversely (w) = 30 tonnes=30×1000=30,000kg The transverse shift of mass (d) = 6.0 meters Pendulum length (L) = 6.0 meters Pendulum deflection (x) = 30 cm = 0.30 meters Step 1: Formula for Metacentric Height…arrow_forwardAnswer the assignment question, expert onlyarrow_forwardA 1 inch rod diameter B 3/4 inch rod diameter C 1/2 inch rod diameter D 3/8 inch rod diameterarrow_forward
