    How to do this question ??

    3. The attempt at a solution

    I know sum of torque and force = 0
    at fapplied i got torque = 25sin(45) * 3.8m = 67.18N ..

    But dont know what to do next !!!

    All they asking for is the torque of the applied force about the pivot.

    So your formula is correct however your value for the perpendicular distance is incorrect. You need to usethe distance from Fapplied to the pivot.

    ohh crapp i have to use distance from pivot which is 3 right ??

    Yes...You need to use distance between the pivot and application of force.
