1.1.18
There are known projections on the coordinate axes Rx = 18H and Ry = 24H of the resultant R flat
Systems of convergent forces F1, F2 and F3, as well as the projections of forces F2 and F3 on the same axes: F2x = -9H, F2y = -
7H, F3x = 12H, F3y = 0. Determine the modulus of force F1. (Answer 34.4)
