=Consider a model of a wing-body shape mounted in a wind-tunnel. The flowconditions in the test section are standard sea-level properties (p 1.225kg/m³)with a velocity of 100 m/s. The wing area and chord are 1.5 m² and 0.45 m,respectively. Using the wind tunnel force and moment-measuring balance, themoment about the center of gravity when the lift is zero is found to be -12.4 N m.When the model is pitched to another angle of attack, the lift and moment about thecenter of gravity are measured to be 3675 N and 20.67 N m, respectively. Calculatethe value of the moment coefficient about the aerodynamic center and the locationof the aerodynamic center.

A hammer strikes a metal disk with 150N of force, temporarily making the 25.0mm3 disk lose 0.2mm3 of volume before it snaps back. If the disk has a top surface area of 120mm2 and completely fits under the hammer’s striking face, what is the relevant elastic modulus of the metal?
