The pipe assembly is subjected to the force of F = {700 i + 800 j - 500 k} N.? This are how I solve 1st I got postion rbc= 0i,.7j-.3k. ThenI cross rbc with F to get my answer Mbc=(-195i-150j-350k)N*m but the computer says my answer is wrong. What I did wrong? Is my answer right or wrong? What is your answer?
