3. Examine your data in Data Table 2 and in Data Table 3. For the data with the smallest percentage difference, compare the total energy at each point. Calculate the sum U₁+Ug at x₁ as ½kx-mgx₁. Calculate that sum at x₂ as ½kx²-mgx₂. Do you expect them to agree reasonably well? Explain why they should or should not be the same. 4. Consider the same data as used in Question 3. Calculate the value of x halfway between x₁ and x₂. Calculate U₁+Ug=½kx² − mgx_for_that point. Do you expect them to agree with the energy calculated in Question 3? If they agree reasonably well, explain why they do. If they do not agree, explain why they do not agree.

As we explained in earlier chapters, the air resistance to the motion of a vehicle is something important that engineers investigate. The drag force acting on a car is determined experimentally by placing the car in a wind tunnel. The air speed inside the tunnel is changed, and the drag force acting on the car is measured. For a given car, the experimental data generally is represented by a single coefficient that is called drag coefficient. It is defined by the following relationship: F, where air resistance for a car that has a listed C, = drag coefficient (unitless) measured drag force (N) drag coefficient of 0.4 and width of 190 cm and height of 145 cm. Vary the air speed in the range of 15 m/s
II Question 2 A process instrument reading Z (volts) is thought to be related to a process stream flow rate V (L/s) and pressure P (kPa) by the expression: Z = aVÞp°. Using the three data points shown in the table above, calculate the constants a, b and c and indicate their units. In this particular case there is no regression to be performed, but only 3 equations in 3 unknowns to solve. 1 1.02 V (L/s) P (kPa) z (volts) 1.20 1.75 11.2 10.2 9.1 2.58 3.72 3.50 ere to search 12

Cages used for supporting bearings in an aero engine have been tested under simulatedoperating conditions. Failures of these bearing cages were recorded after the followingengine running hours:1420, 940, 2620, 705, 360, 1185, 1410, 1950, 2730, 2050, 525, 1465, 925.The total number of bearing cages tested was 64. The remaining 51 cages did not fail bythe time the tests were stopped at 2730 hours. Determine:(a) the minimum life.(b) the characteristic life (after the minimum life), to the nearest 100 hours*.(c) the shape factor. From this, comment on the nature of the failure of these bearing cages.
11 Sunco Oil has refineries in Los Angeles and Chicago.The Los Angeles refinery can refine up to 2 million barrelsof oil per year, and the Chicago refinery up to 3 million.Once refined, oil is shipped to two distribution points:Houston and New York City. Sunco estimates that eachdistribution point can sell up to 5 million barrels per year.Because of differences in shipping and refining costs, theprofit earned (in dollars) per million barrels of oil shippeddepends on where the oil was refined and on the point ofdistribution (see Table 51). Sunco is considering expandingthe capacity of each refinery. Each million barrels of annualrefining capacity that is added will cost $120,000 for the LosAngeles refinery and $150,000 for the Chicago refinery. Uselinear programming to determine how Sunco can maximizeits profits less expansion costs over a ten-year period.

C Dynamic Analysis and Aeroelasticity SECTION B Answer TWO questions from this section ENG2012-N The moment of inertia of a helicopter's rotor is 320kg. m². The rotor starts from rest and at t = 0, the pilot begins by advancing the throttle so that the torque exerted on the rotor by the engine (in N.m) is modelled by as a function of time (in seconds) by T = 250t. a) How long does it take the rotor to turn ten revolutions? b) What is the rotor's angular velocity (in RPM) when it has turned ten revolutions?
