Suppose that aaa = 190 mmmm. (Figure 1)

Figure

1 of 1A cross-section of a beam is shown on the xy-plane. The x-axis is directed to the right and the y-axis is directed upward. The cross-section consists of two parts. The first part is a 18-millimeter wide rectangle with a a vertical side of length a placed so that its left side lies on the positive y-axis and the bottom left corner is at the origin. The second part is a 18-millimeter high rectangle with a horizontal side of length a placed so that its left side lies on the positive x-axis and the left side touches the right side of the first rectangle. The vertical side of the first rectangle is much greater than its horizontal side. The horizontal side of the second rectangle is much greater than its vertical side. The x-prime-axis is parallel to the x-axis and located at a distance y overbar above the x-axis and the y-prime-axis is parallel to the y-axis and located at a distance x overbar to the right of the y-axis. The x-prime-axis intersects the y-prime-axis at point C.

A nonuniform beam 4.45 m long and weighing 1.08 kN makes an angle of 25 ∘ below the horizontal. It is held in position by a frictionless pivot at its upper-right end and by a cable a distance of 3.06 m farther down the beam and perpendicular to it (see Figure 11.31 in the textbook). The center of gravity of the beam is a distance of 1.97 m down the beam from the pivot. Lighting equipment exerts a downward force...
