There is also a focus on economic, commercial, and people-to-people ties. There are an estimated four million U.S. citizens of Philippine ancestry in the United States, and more than 220,000 U.S. citizens in the Philippines, including a large presence of United States veterans. An estimated 650,000 U.S. citizens visit the Philippines each year. Many people-to-people programs exist between the United States and the Philippines, including Fulbright, International Visitor Leadership Program, and the Kenney-Lugar Youth Exchange and Study program.
The rate or spring constant of a spring is the change in the force it exerts, divided by the change in deflection of the spring. That is, it is the gradient of the force versus deflection curve.
I've always been taught that the spring constant $k$ is a constant â that is, for a given spring, $k$ will always be the same, regardless of what you do to the spring. My friend's physics professor gave a practice problem in which a spring of length $L$ was cut into four parts of length $L/4$.ote that the spring constant $k = \frac{EA_0}{L_0}$ where E is the Young's modulus of the material (constant, at least in one direction), $A_0$ is the unstretched cross sectional area, and $L_0$ is the unstretched length of the ideal spring.
