Homework Statement:

How much moment (or torque) is produced about point O by the wrench in the situation below?

Relevant Equations:

Varignon’s theorem (principle of moments) (sum of forces and moments must be equal)
Here's a diagram of the problem. There are 3 possible solutions: 163 in-lb clockwise, 163 in-lb counterclockwise, 82.7 clockwise or none of them. After attempting the problem the closest I got to was 82.7 but that was wrong so I'm still stuck.

Welcome, Rildude :cool:

Please, show us your work so far.

If the applied 20 pounds of force were perfectly vertical, how much the value of the resultant torque would be?
From that value, how much less torque on O the 30-degree direction of application and the 1-inch off set would cause?
