Document Summary
Example 5-x: a 1. 8 pound vertical force is applied to the knob (d) of the window opener mechanism when the crank bc is horizontal. Find the moment of the force about point a and about line ab: note: bc is parallel to y axis, cd is parallel to the x axis and. Ab is 30 degrees above the x axis, ab is 2 inches, bc is 3 inches and cd is 1 inch. 5. 2: statically indeterminate objects: define: constraints: forces some sort of object to not be able to move in a certain direction, redundant constraints: caused by redundant supports. Redundant support: more supports than necessary to hold the body in equilibrium. If more supports than necessary, then the body is statically indeterminate. Example: two redundant supports, statically redundant to the second degree, degree of indeterminacy is two. Homework 8, homework eight, hw8: chapter 5: 3,18,34, 43, 55, 60, 81, 93, 95, 100.
