The internal shear force V at a certain section of a steel beam is 80 kN, and the moment of inertia is 64,867,500 mm4. Determine the horizontal shear stress at point H, which is located L = 39 mm below the centroid.

For a beam with the cross-section shown (w = 16.0 in. and h = 19.5 in.), find the distance from the bottom surface of the beam to the centroid.

Figure 11.6: IS Curve Consider the IS curve in Figure 11.6. If the interest rate increases and there is a positive aggregate demand shock, the economy would move from point e to point:
