The yield strength for an alloy that has an average grain diameter of 6.0 × 10-2 mm is 139 mpa. at a grain diameter of 6.5 × 10-3 mm, the yield strength increases to 268 mpa. at what grain diameter, in mm, will the yield strength be 238 mpa? d=

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].

Sodium chloride, nacl, is formed when a sodium atom transfers its electron to a chlorine atom. the difference in charge between the two atoms creates a(n) attraction that bonds them together.
