Chapter 3, Problem 3.43P

A catheter is inserted into the vena cava of an animal to measure the venous blood pressure variation with breathing. The other end of the catheter is attached to a pressure transducer and conditioning system to record the measured pressure. The catheter has a known natural frequency and damping ratio of 4 rad/s and 0.2, respectively, while these values for the pressure transducer are 2(XX) rad/s and 0.7. The venous pressure is expected to vary as p(t) = 10+ 1.5 sin 2t in mm Hg. Find the time-dependent magnitude attenuation and time delay of the output pressure signal. Assume Khysteai = 1 mm Hg/mm Hg and linear behavior of the system.

An application demands that sinusoidal pressure variation of 250 Hz be measured with no more than 2% dynamic error. In selecting a suitable pressure transducer from vendor catalog, you note that a desirable line of transducer has a fixed natural frequency of 500 Hz but that you have a choice of transducer damping ratio of between 0.5 and 1.5 in increments of 0.05. select a suitable transducer. The value of damping ratio is between the following values Select one: a. 0.707 and 0.807 b. 0.5215 and 0.5625 c. 0.631 and 0.692 d. 0.2356 and 0.5625
An undamped simple harmonic oscillator has mass 2.0 kg and spring constant 50 N/m. The initial displacement from equilibrium (at time t = 0) is 0.30 m and the initial velocity is 2.0 m/s. %3D 1. Determine the angular frequency (in rad/s), the frequency (in Hz), and the period (in s). Determine numerical values (not in terms of .) Determine the displacement in the form x(t) = Acos(mot) + Bsin(@ot). That is, solve for A and B in meters, and write oo in radians per second.
The temperature of a room is 15 °C A temperature sensor has a time constant of 0.1 s and K = 5 mV/°C is applied to measure the temperature. The system is then processed by a second order amplifier that has a K = 1 V/V, a natural frequency of 40 Hz, and a damping ratio of 0.1. What is the amplitude of the output signal at steady state (in mV)?
