• The following figure shows a small gate attached to two couples. The door needs a resultant moment of 121 N-m counterclockwise to be able to open when rotated about pin A. The purpose of this problem is to calculate what force F2 is necessary for the gate to open with the specified moment. The magnitude of the force F1 is equal to 458 N (Note that due to the distances provided, it is not necessary to use the principle of moments for couples and that not all dimensions will be needed).
• What is the magnitude of the force F2 necessary for the gate to open? This will be the answer that you will offer in the numeric entry of this question.
