Problem 1.2 Force Magnitude Minimization The boat is to be pulled onto the shore using two ropes. If the resultant force is to be 80 lbs. directed along the keel a - a as shown, determine the magnitudes of forces T and P acting in each rope and the angle θ of P so that the magnitude of P is minimum. Figure P1.2: Problem 1.2
Problem 1.3 Force Vector Addition Determine the magnitude of the resultant vector F R = F 1 + F 2 and its direction, measured counterclockwise from the positive x -axis. Figure P1.3: Problem 1.3

### What students are saying

• 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.
