If I have a linear system with one negative eigenvalue and another eigenvalue of zero, what does that mean for the stability of the equilibrium. Also, then if I have a nonlinear system with one negative eigenvalue and another eigenvalue of zero, what does it mean for its equilibrium stability. What it be the same for both nonlinear and linear?

To understand how to use conservation of angular momentum to solve problems involving collisions of rotating bodies. (Figure 1) Consider a turntable to be a circular disk of moment of inertia It rotating at a constant angular velocity ωi around an axis through the center and perpendicular to the plane of the disk (the disk's "primary axis of symmetry"). The axis of the disk is vertical and the disk is supported by frictionless bearings. The motor of the turntable is...
Turntable question..
I hate turntable questions I can not understand this one atallConsider a turntable to be a circular disk of moment ofinertia rotating at a constant angular velocity around an axis through the center and perpendicular tothe plane of the disk (the disk's "primary axis of symmetry"). Theaxis of the disk is verticaland the disk is supported byfrictionless bearings. The motor of the turntable is off, so thereis no external torque being applied to the axis.Another disk (a record) is dropped...

Market Capitalization I do understand that market capitalization is defined as the value of the outstanding stock of a company in the market, but when the market of that company goes down, does the value of the company also go down, or are the assets lost? I am not really understanding how that works. A company does need to have a high market of resources in the business industry, and they need the financial backing in the business world, otherwise,...

The directors of Siedu Ltd. have recently announced a record increase in payment for the half-year ended 30th September 2005. On announcement date, the company’s equity share price was ¢3000, its highest level for many months, giving it an equity market capitalization of approximately ¢480 billion. On the same day as the profits announcement, the directors declared their intention of raising funds via a rights issue in order to finance a major expansion in Siedu Ltd’s overseas operations. Their aim...
