Perform the partial fraction expansion of the following transfer function and find the impulse response:
G(s) = (s/2 + 5/3) / (s^2 + 4s + 6)
G(s) =( 6s^2 + 50) / (s+3)(s^2 +4)
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…
