Step 1
- From the diagram, the coordinates of point B relative to O are (1.2 m, 0.2 m, 0.4 m). - Therefore, the position vector \(\vec{r}\) is: \[ \vec{r} = 1.2\hat{i} + 0.2\hat{j} + 0.4\hat{k} \, \text{m} \] Show more…

The direction cosines of the force F are cos ̘_x = 0.818, cos ̘_y = 0.182, and cos ̘_z = -0.545. The support of the beam at O will fail if the magnitude of the moment of F about O exceeds 100 kN-m. Determine the magnitude of the largest force F that can safely be applied to the beam.
