1. The problem statement, all variables and given/known data A force of 56 pounds acts on the pipe wrench shown. find the magnitude of the moment about O by evaluating || OA x F || 2. Relevant equations || OA x F || 3. The attempt at a solution First I tried to find my vector component for Force which I got -56 [ cos(30)i + sin(30)j ] Since my force on wrench is 56 pounds and it is in a downward vertical I used F=-56 To which my vector for F simplified to = -28sqrt(3)i -28j Now I needed to find a component vector from O to A. Which I initially thought would be 0i+0j +(3/2)k Since 3/2 ft (18in) is how long my wrench is? after I get my two vector components I use the cross product and find the magnitude. I just needed some guidance on my vectors for F and vector(OA) .
