A linear variable displacement transducer (LVDT) converts linear displacement (the input) into an AC voltage (the output), and the RMS voltage output increases linearly with displacement. The manufacturer claims a sensitivity of 0.0100 V/mm. (a) For a maximum displacement (input span) of 25 mm, calculate the ideal output span voltage. (b) Suppose the instrument is faulty, and the actual sensitivity is 0.0103 V/mm. Calculate the output span for this case. Also calculate the percentage error in output span. Is this a bias or a random (precision) error

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Air flows over a heated plate àt a velocity of 50m/s. the local skin factor coefficient at a point on a plate is 0.004. estimate the local heat transfer coefficient at this point. the following property data for air are given: density = 0.88kg/m3 , viscosity 2.286 x 10 ^-5 kgm/s , k = 0.035w/mk ,cp = 1.001kj/kgk. use colburn reynolds analogy.

Prove the equivalence between the two statements of the 2nd law of thermodynamics (i. e., a violation of one statement leads to the violatio the other statement)
