Lecture 19: Examples on Moment of a Force About a Specified Axis

2. Lecture 19 Objective
to demonstrate by example finding the moment of a force about a specified axis

3. Mid-Term
Concepts up to and including this lecture could be covered in the October 18 or October 22 mid-term

4. Example 19-01
A force is applied to the valve stem to open a buried gas valve. Find the magnitude of the moment of this force about the vertical z-axis of the valve.

5. Example 19-02
A force F of 80 lb acts along the edge DB. Find the magnitude of the moment of this force about the axis AC.
