The derivation of the field-controlled motor model in Section 6.5 neglected the elasticity of the motor-load shaft. Figure P6.37 shows a model that includes this elasticity, denoted by its equivalent torsional spring constant kT . The motor inertia is I1, and the load inertia is I2. Derive the differential equation model with 2 as output and v f as input.
Monday, September 28, 2015 Reading Questions Friedman 1) Friedman believed that the purpose of a firm was to act based around the interests of the firm in order to produce maximum profit and benefit of its employees. Friedman does limit this definition to exclude social responsibility stating that it is not the main goal or interest of the firm because you would be spending that of which you have no right to dictate and therefor out of the realm of your job duties. 2) A manager has a specific job title, and that as a general statement is to act in the best interests of his firm, excluding social responsibility, in order to achieve maximum profit.
