b) A linear variable displacement transducer (LVDT) senses displacement and indicates a voltage output, which is linear to the input. Figure 1 shows an LVDT setup used for static calibration. It uses a micrometre to apply the known displacement and a voltmeter for the output. i) Suggest the independent, dependent and extraneous variables in this calibration. ii) Indicate the basic functional elements of the device in Figure 1 in the form of block diagram. Micrometer Fixed mounts Connector Excitation voltage in Figure 1 Primary coil LVDT E Output voltage 10.135 Voltmeter Secondary coil Core

How do you transform from ECEF to ECI? I have the r vector in ecef and eci and the modified julian date. How do you use the rotation matrices to get to r_eci. r_ecef = [-1016.215157; 5431.875007; -3174.1]; r_eci = [-2010.4; -5147.4; -3174.1]; MJD = 57923.6666667; % Modified Julian Date

A) Assuming that no inputs are present to a first-order and a second-order systems, mention two fundamental differences between the two systems. B) Determine the damping ratio and natural frequency of the single-loop RLC electrical circuit system shown below. d²1 dI I + R + = dt² dt с L E(t). C) State two distinctions between odd and even functions, and name and sketch a function that's neither odd nor even. D) What is the frequency in Hertz and the amplitude of the 5th term (i.e. the 4th harmonics) of the following signal? 4 2π 10π == - sin TT 4 бп y(t) (² t) + 37 sin (17) 4 + sin 5π (10+) +. 10 10
