The beam is supported by a roller at B and a pin at C and is subjected to the distributed load shown with intensity w = 280 N/m. The maximum positive and negative internal bending moments are critical factors the design of the beam material and geometry. On your written homework draw a full free body diagram of the beam including all reaction forces. Directly under the free body diagram, draw a shear and bending moment diagram. Using your diagrams, determine the largest positive and negative internal bending moments that occur in the beam and the points along the length where each occurs. Take z = 0 to be at point A at the left edge of the beam.

Transcribed Image Text:The beam is supported by a roller at B and a pin at C and is subjected to the distributed load shown with
intensity w = 280 N/m. The maximum positive and negative internal bending moments are critical factors
in the design of the beam material and geometry.
On your written homework draw a full free body diagram of the beam including all reaction forces. Directly
under the free body diagram, draw a shear and bending moment diagram.
Using your diagrams, determine the largest positive and negative internal bending moments that occur in
the beam and the points along the length where each occurs. Take z = 0 to be at point A at the left edge
of the beam.
