owhh.. how about to solve this question:
determine the magnitude and direction of P so that the resultant of P and the 900N force is a vertical force of 2700N directed downward.
is it using the same method also? it's almost the same right?
[FONT="Fixedsys"][SIZE="3"]can anyone explain how to solve this problem in complete details? i don't understand the explanations. i have the same problem too. :confused:
