Hook in a Ceiling

ID: zl03l0y8o4

Problem: Two cables hang from a hook in a ceiling and pull on it with \(\mathbf{T}_1 = \{120\,\mathbf{i} - 160\,\mathbf{j} - 600\,\mathbf{k}\}\,\text{N}\) and \(\mathbf{T}_2 = \{-300\,\mathbf{i} + 200\,\mathbf{j} - 400\,\mathbf{k}\}\,\text{N}\). Find the resultant force on the hook and its angle from the downward vertical.
