Question 2 - 70 Marks A hydraulic car lift system is shown schematically in Figure 1. The system is being designed to lift a 1500 kg car via two pistons (driven pistons) located underneath the wheels of the car (distributing the weight of the car so that half is on each piston). The cylindrical pistons each have a diameter of 10cm. The hydraulic system will be driven by a person sitting (or standing) on the driving piston. The car weighs...

Question 1 (40 points): The figure shows a rigid rod of length t = 1 m whose end B is connected to a roller by a pin joint which is in a vertical guide and the other end, A, is controlled by a piston whose cylinder is fixed to the ground. There is a pin connection between the piston and rod at A. For the instant when s = 0.293 m, is increasing at a rate s = 0.2 m/s...

kg/m^3.
1. (15 marks): The open cylindrical tank in the figure contains water and is being filled as shown. Assume incompressible flow, with water = 1000 kg/m3. a) Write the mass transport equation and note that the flow may not be steady, which implies that the rate of change of mass in the control volume needs not be...

Question 3 : Solow model with long-run TFP growth [20 marks] Suppose output is given by Y = K}(AN) As in the basic model, the workforce grows at rate n, capital depreciates at rate d and the savings rate is s. In addition, suppose that TFP grows at a constant rate g. That is: ΔΑ A9 We will refer to the product AN as the "effective workforce". It follows that the effective workforce grows at rate n+g. a. Express the...
