A propped cantilever beam is loaded by a bending moment of the magnitude M3 at the point B as shown in Figure Q1. The cross-section of the beam is a rectangle of the width w and the highth that are constant along the length of the beam L. The beam material's Young's modulus is Q. Figure Q1 Assuming the positive deflections and positive vertical reaction forces are upward, calculate o the value of the reaction forces at points A and B o the absolute value of the reaction bending moment at point A

Transcribed Image Text:A propped cantilever beam is loaded by a bending moment of the magnitude M3 at the point B as
shown in Figure Q1. The cross-section of the beam is a rectangle of the width w and the hight / that
are constant along the length of the beam L. The beam material's Young's modulus is Q.
Figure Q1
Assuming the positive deflections and positive vertical reaction forces are upward, calculate
o the value of the reaction forces at points A and B
o the absolute value of the reaction bending moment at point A
Transcribed Image Text:(b)
Using the provided data:
• cross-section width w = 19 mm,
cross-section hight h = 72 mm,
length of the beam L=2 m,
• beam material's Young's modulus Q-201 GPa,
applied bending moment MB = 5 kN.m
The value of the deflection at Point B caused by MB (Part I) can be calculated as
mm
