QUESTION:
Determine the internal normal force, shear force, and moment at points E and F of the compound beam. Point E is located just to the left of 800 N force.
ANSWER:
Step 1 of 9
From the portion of BC of the diagram,
The component of the force along the y-axis is,
The net moment about the point B (by taking the anticlockwise direction as positive and clockwise as negative) is,
Where is the component of reaction acting at the point C along the y-axis,
The net moment about the point B is zero, thus,
