Igetit! thanks for the amazing explanation :)

I've had to conduct an experiment with strain gauges attached to each member and when I've calculated the forces in the members I've come out with really large forces in comparison to the applied force.. how does this work out?

thank you for replying so fast. i see that now. my concern is that i seem to answer the questions a bit backwards to my lecturer and i'll show you what i mean- i use r x F because it's like that in hibbeler but if i use her method it doesn't align. i don't know if there actually is a difference...

hi guys In my lecture we were told to just sum the components of a force ( * respective x y distances) to obtain moment. I've been trying to do practice questions in hibbeler but my answers are always wrong and I've found that it;s because of the way they're summed/ subtracted. Here's the...
