Please solve these questions in details and fully explaination. Thanks so much in advance.

1. Given that F1 2 3O kN, F2 = 20 kN, L = 3 m, and a = 25 degrees, determine the magnitude of the resultant moment produced by the forces about point 0 in kN-m. F: + L ./ 2. Given that a = 40, L1 = 0.2 m, and L2 = 0.15 m, determine the magnitude of the vertical force F (in Newton) acting on the handle of the wrench so that this force produces a component of moment along the AB axis (x-axis) of the pipe assembly of (N01: {-Gi} Nm. Both the pipe assembly ABC and the wrench lie in the x-y plane. Suggestion: Use a scalar analysis
