A liquid film is suspended on a rectangular wire frame. The length of the movable wire is 2 in. and the other dimension initially is 6 in. The movable wire is displaced by 1 in. by an applied force (making the rectangular frame 7 in. by 2 in.). The surface tension remains constant at 2.5 x 10-4 lbf/in. Determine the work done in stretching the film.
