The boat is to be pulled onto the shore using two ropes. If the resultant force is to be 400N, directed along the keel, determine the magnitudes of forces T and P acting in each rope and the angle theta of P so that the magnitude of P is a minimum. T acts at 30 degrees from the keel.


How can I determine the value of P if it is a minimum? Do minimum forces make a specified angle with each other?

It has to pull up with the same amount of force that the other one pulls down.

..while at the same time adding up to a horizontal force of 400N.
