An experiment was carried out on a SDOF system to estimate the natural frequency and damping. The time history plotted below has the response in centimetres and the time in seconds, as shown in Figure Q10 below. Estimate values for the following and choose the nearest values from the list given below: the damped natural frequency in Hz; the damping ratio using the logarithmic decrement method; and the natural frequency in rad/s.

Find the differential equation and define the type of the control low. Draw the control structure. Problem 2 A pressure is measured with a sensor with range-1 to 10 bars. If it generates a current with range between 4 and 20 mA, please calculate the pressure if 10 mA is measured at the PLC Input;
The ability of the instrument to give same output for same input when the conditions are different is known as O a. Reproducibility Ob. Resolution O. Accuracy O d. Repeatability Jis used to convert resistance value into voltage value. response is the response of a system after the transient response.
