Determine the moment of each force about the point of contact A on the ground. 2. The 70-N force acts on the end of the pipe at B . Determine the angles Ɵ (0 ° Ɵ 180 ° ) of the force that will produce maximum and minimum moments about point A. What are the magnitudes of these moments? Ans: M A = 37.9 Nm F c =82.2 N

    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.
