    Just copy and paste the question.

    Fig. 3.1 shows a boat that has been lifted out of a river. The boat is suspended by two ropes. It is stationary.

    Determine
    (i) the moment of the weight of the boat about the point P
    (ii) the tension T1
    (iii) the tension T2

    the clockwise moments about P ( or any other point ) must equal the anticlockwise moments.

    the upward forces must equal the downwards forces.

    use what i suggested above... you get 2 equations ... solve the first equation to find T1 and use that to find T2 in the second equation.
