What is Exotic's profit (or loss) at the profit-maximizing output level? $ Suppose that the federal government announces it will sell beryllium, from its extensive wartime stockpile, to anyone who wants it at $5.98 per pound. Under these conditions, Exotic Metals maximizes profits by producing pounds per period.

Question 2 [30 marks] t of inertia J) Rotor in bearings Figure 2: turbine rotor mounted in bearings Consider a turbine rotor mounted in bearings as shown in Fig. 2. The viscous fluid (lubricant) in the bearings offers viscous damping torque during the rotation of the turbine rotor. Assuming the mass moment of inertia of the rotor about the axis of rotation as J and the rotational damping constant, ct, of the bearings as the application of Newtons second law of motion yields the equation of motion of the rotor as: J+c=0 (2) Where w is the angular velocity of the rotor= dt angular velocity, and the external torque applied to the system is assumed to be zero. We assume the initial angular velocity, (t = 0) = o as the input and the angular velocity of the rotor as the output of the system. a) Find the final equation of the analytical solution of the motion, if we assume the general form is: wt=Aest (3) Where A and s are unknown constant. By using the initial condition, (t = 0) = Wo, equation (3) can be written as w(t=Wgest (4) The analytical solution can be obtained by substituting the above general form into equation (2) and then finding the unknown value, s at time,t=0. To avoid no motion of the rotor the must not equal to zero ( 0 [CLO1|6 marks] b) Using appropriate numerical method, find the angular velocity, (t) using equation (2) for time 0 to 3s with step time of 1s. Let =12rad/s , c=0.5Nms/rad and J=1kgm2. [CLO2 | 12 marks] c) Find the error between results in (b) and the analytical method and gives two suggestions on how to improve your estimation accuracy.
