    Hi everyone...how I wish someone could share their knowledge and help me through this..im having a difficulty on finding the right FBD of this problem.. I tried solving it but still I couldn’t get the right answer… anyone please help?.

    Here is the question:

    The window washer A and B support themselves and the 15-kg uniform plank CD by pulling down on the two ropes.

    Determine (a) the tension in each rope; and (b) the vertical force that each man exerts on the plank.

    (The required at question “b” are the normal force of A and B.)
    Please?.. it would be very much appreciated..
