For a moment,I felt so dumb.I did my applied mechanics homework and when I thought I could do it after some help from Shujun,I'm wrong.I can draw the free-body diagram and guess what,I couldn't solve the sum.I gave up and continue to do my PFA,which I thought would be easier.Who knows the referencing to the colour chart is such a tedious work.I'm stressed to a level that I completely forgot how to operate Microsoft word.I had to follow guidelines gave to me by Shujun.
I'm dumb,no arguements.
