1. The problem statement, all variables and given/known data This is the force table lab that we are doing. [itex]F _1 = 300g @ 30^o[/itex] [itex]F _2 = 450g @ 110^o[/itex] [itex]F _3 = 400g @ 230^o[/itex] [itex]F _4 = 270g @ 298^o[/itex] Finding resultant force using Component Method 1. Express each force F1, F2, and F3 in unit vector notation. Take the origin to be at the center of the force table (at pivot point) with the +x axis along [itex]0^o[/itex] and +y-axis along [itex]90^o[/itex]. 2. Use the component method to obtain the resultant force vector Fcomp in unit vector notation. Calculate the magnitude and direction. 2. Relevant equations sinθ=opp/hyp cosθ=adj/hyp F=ma 3. The attempt at a solution His directions are kind of confusing to me. For the step 1 I found: I converted the mass into kg and then found the force. [itex]F _1 = 2.94N [/itex] [itex]F _2 = -4.41N [/itex] [itex]F _3 = -3.92N [/itex] Then I express each force into unit vector notation. [itex]F _1 = 2.94cos30i +2.94sin30j [/itex] [itex]F _2 = -4.41cos70i +4.41sin70j [/itex] [itex]F _3 = -3.92cos50i -3.92sin50j [/itex] Did I do this part right? Please check it for me. I don't know where to start for step 2. Do I find F4?
