Problem 2-12 (page 26) Solution:
The cable exerts a force of 600 N on the frame. Resolve this force into components acting (a) along the x and y axes and (b) along the u and v axes. What is the magnitude of each component? Solution:

Problem 2-16 (page 26) Solution:
If the resultant FR of the two forces acting on the jet aircraft is to be directed along the positive x axis and have a magnitude of 10 kN, determine the angle  of the cable attached to the truck at B such that the force FB in this cable in a minimum. What is the magnitude of force in each cable when this occurs? Solution:

Problem 2-29 (page 35) Solution:
