Transcribed Image Text:**Problem 4.3** - Replace the 2-lb force acting on the end of the bottle opener with an equivalent force and couple moment acting on the underside of the bottle cap at A.
**Diagram Explanation:**
- The diagram illustrates a bottle opener located above a bottle cap.
- Point A represents the pivot or the underside of the bottle cap where the equivalent force and couple moment are to be considered.
- A force of 2 lb is applied downward at the end of the bottle opener, denoted by point B.
- The distance from point A to point B is given as 3 inches.
- The 2-lb force is shown as a vector pointing downwards and to the right.
**Objective:**
- To replace the given 2-lb force with an equivalent force and couple moment at point A on the bottle cap. This involves maintaining the same mechanical effect as the original force does when applied at point B.
Expert Solution

Step 1
Shifting the force Parallel to its line of action and calculate the equivalent moment. The equivalent is equal to force times the distance of shift.
