1: Bending moment in a beam was determined to be M(x) = 2000 (x – 2) (N∙m), where x varies from 0 to 2.0 m. Write the angle of rotation (??) as a functions of x, if EI = 2∙106 N∙m2, and ?(0) = 0
2. For the beam in above Problem, calculate the strain energy for x from 0 to 2.0 m.
1) We have
M= 2000(x -2) = 2000x - 4000
Integrate both sides
Also
=> C = 0
Therefore
2) Strain energy is given by
= 5.33 N-m
