The mechanical structure of a rotational system is given as shown. K shows the spring coefficients, B shows the viscous damping coefficients, N shows the number of theeth of gears and J shows the moment of inertia. An external torque T(t) is applied to the system as shown. Draw the equivalent system(without gears) using the reflecting impedances

Draw the circuit and write the value of each element, determine the currents and voltages of the elements using KVL, Devreyi izin, her elemann deerini yazn, Kirchhoff gerilim yasasn kullanarak evre denklemini belirleyin ve pasif devre elemanlarnn akm ve gerilimlerini hesaplayn. V 30 V, V2 12 V R1 Q2, R222, R33 2, b) Calculate all absorbed powers,
Draw the circuit and write the value of each element, determine the currents and voltages of the elements

The current in a 200 mH inductor is i 75 mA, t0 i (B cos(200t) B sin(200t))e 50 A, t20. The voltage across the inductor (passive sign convention) is 4.25 V at t 0. Calculate the power at the terminals of the inductor at t 25 ms. (Note that this will require you to solve for the values of B and 82.) State whether the inductor is absorbing or
The current in a 200 mH inductor is i = 75 mA, t0; i =(B cos(200t) + B sin(200t))e 50 A, t20. The voltage
