1. Four students are trying to move a table from one corner of the classroom to another, as illustrated in the figure (top view). The students hold the table from points A, B, C, and E, and apply pulling forces with magnitudes 20 N, 35 N, 5 N, and 35 N, respectively. Compute the resultant moment (in vector form) of these four forces, a. About point A, using the scalar method, b. About point D. using the scalar method.
