The width of the fuel region is 2a, and the fuel plate can be considered very thin since the width of the fuel is much smaller than

When the damping ratio of a second-order system is reduced while maintaining the same natural frequency, how will the setting time, peak time, and the percent overshoot be affected? Justify your conclusion mathematically.

Given a structural member shape made from a given material determine the following when the member is loaded to its yield strength. 1. Determine the force F to reach the members material yield strength. 2. Report the deformation and strain of the member at yielding. (Round to the nearest four decimal places) The member shape and material are

Consider a finite wing with an aspect ratio of 8 and an induced drag factor 8 0.055. The airfoil section is assumed to be thin and symmetric. Calculate the lift coefficient and induced drag coefficient for this finite wing when it is at an angle of attack of 5 degrees. Assume 8 T ao and slope a Note that ao is the lift curve slope of an
