Chapter 6: Analysis of Structures

=> Improperly constrained Indeterminate & Partially constrained (i) V 1= V 2 < U => Infinitely many solutions possible (ii) V 1 < V 2 => No solution exists Note : In this procedure, it is better not to reduce the number of unknowns or number of equations by using properties of 2 -force or 3 -force members.

ELEVEN REASONS WHY PRESIDENTIAL POWER INEVITABLY …

presidential power is unduly constrained, even in the areas of foreign policy and national security. John Yoo, Jefferson and Executive Power, 88 B.U. L. REV. 421 (2008). But if the ability of an individual to achieve greatness in office is a function of the power of that office, then consider the record of Congress.

Usually a body is constrained against motion using supports. The forces from these supports, acting on the body are external to the body and must be included in the FBD. The magnitude of these support forces are usually unknown and are obtained by solving the equilibrium equations. Some examples of these support reactions are:
