Question

Write out a hand solution for the following problem: There is a force acting at point A. The force can be written as FA = {-243 i -38 j -111 k} lb As a reminder to all (especially those of you not familiar with the U.S. Customary system of units, "lb" is the abbreviation for the unit of force called, "pound." There is also a line, AB, that starts at A and can be written as rAB = {1.22 i + 8.33 j +3.41 k} ft "ft" is the abbreviation of the unit "feet" For the problem, please complete the following:

Draw a diagram of the problem. Use a straight edge. Determine the magnitude of the Force. Determine the angle between the force and the line (hint, use the concept of the Dot Product) Determine the value of the component of the force that is acting along the line AB.
