20.84. Set Up: Segments bc and cd each have length Draw each segment in the plane of the page. The direction of is given by the right-hand rule. Solve: (a) segment ab (Figure 20.84a): is in the direction. so segment bc (Figure 20.84b): is in the direction. segment cd (Figure 20.84c): is parallel to the yz plane, midway between the and axes. segment de (Figure 20.84d): is in the direction. segment ef (Figure 20.84e): so (b) The force on segment cd has a component of 4.24 N in the direction and a component of 4.24 N in the direction. Adding the forces on the segments therefore gives a net force of 4.24 N, in the direction. Figure 20.84 20.85.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
