Problem 1.237
Three forces are applied to a square plate as shown in Fig. 1.53. Find the modulus, direction, and the point of application of the resultant force, if this point is taken on the side \(B \hat{C}\).
1.237. \(F_{\text {res }}=2 F\). This force is parallel to the diagonal \(A C\) and is applied at the midpoint of the side \(B C\).
