The single degree of freedom (SDOF) system that you studied under free vibration in Assignment #3 - Laboratory Component has been subjected to a strong ground motion. The acceleration at the base (excitation) and the acceleration at the roof (response) of the SDOF system was recorded with sampling rate 50 Hz (50 samples per second, or dt= 0.02 seconds). The file ElCentro.txt includes the two columns of acceleration data. The first column lists the acceleration at the base of the SDOF system. The second column lists the acceleration at the roof of the SDOF system. (a) Plot the time histories of the recorded accelerations at the base and at the roof of the SDOF system. (b) Compute the acceleration, velocity and displacement time histories of the roof of the SDOF system subjected to the recorded base acceleration using the Central Difference method.

Assume three cases of damping ratio: Case (A) ξ = 0%; Case (B) ξ = 2%; Case (C) ξ = 5%. The systems are initially at rest. Thus, the initial conditions are u(t = 0) = 0 and ̇u(t = 0) = 0. The systems are subjected to the base acceleration that was provided in the ElCentro.txt file (i.e., first column). For the systems in Case (A), Case (B), and Case (C) and for each natural period compute the peak acceleration, peak velocity, and peak displacement responses to the given base excitation. Please, use the Newmark method for β = 1/4 (average acceleration) to compute the responses. Create three plots with three lines in each plot. The first plot will have the peak accelerations in y-axis and the natural period of the system in x-axis. The second plot will have the peak velocities in y-axis and the natural period of the system in x-axis. The third plot…arrow_forwardDetermine the resultant stress at points P and Q.arrow_forward

- A vertical .2m by .2m square plate is exposed to saturated water vapor at atmospheric pressure. If the surface temperature is 80 degrees C and the flow is laminar, estimate the loal heat transfer coefficents at the middles and at the bottom of the plate.arrow_forwardA transformer that is 10 cm long, 6.2 cm wide, and 5 cm high is to be cooled by attaching a 10 cm by 6.2 cm wide polished aluminum heat sink(emissivity=.03) to its top surface. The heat sink has seven fins, which are 5 mm high, 2mm thick, and 10 cm long. A fan blows air at 25 degrees C parallel to the passages between the fins. The heat sink is to dissipate 12W of heat, and the base temp of the ehat sink is not to exceed 60 degrees C. Assuming the fins and the base plate to be nearly isothermal and the radiation heat transfer to be negligible, determine the minimum free-stream velocity the fan needs to supply to avoid overheating. Assume the flow is laminar over the entire finned surface of the transformer.arrow_forwardI need a mechanical engineering expert to solve this question,no Ai pleasearrow_forward
