Unformatted text preview: . In other words, the vertical displacement at A depends on the horizontal distance times δθ and the horizontal displacement at A depends on the vertical distance times δθ . This method gives results identical with the differential calculus method, albeit without the minus signs that sometimes appear. Your active force diagram should clearly show the proper directions, however, and allow you to use the proper sign for the virtual work term....
