Mr. Goode replaced his old barn. He built a barn 48 feet wide and 56 feet long. He has two outside sections three tiers high and the center section four tiers high. He used 3X6s for the tier poles that sell for $2.05 a board foot. The tier poles are placed 48 inches apart, and he did not need one on the outside because the frame of the barn serves as a tier pole. What did the tier poles cost for the barn?

A transformer circuit which accounts for magnetization and core losses is presented in the following figure.
Voltage, Vin, is applied to the transformer primary side coil which consists of a series resistance and inductance, R1 and L1. The secondary side coil of the transformer is also modeled as a series resistance and inductance, R2 and L2. The magnetization and core losses in the core of the transformer are modeled with Lc and Rm. The impedance diagram for the transformer is created by replacing each element of the circuit with its associated impedance. The impedance of each resistance, Ri, is denoted as ZRi, and the impedance of each inductance, Li, as ZLi.
Draw the impedance diagram for the transformer system.
Draw the block diagram from the impedance diagram
From the block diagram compute the system equation relating the input, Vin, to the output, I2.
