1. An 11-m beam is subjected to a load, and the shear force follows the equation V(x) = 5+ 0.25x2 where V is the shear force and x is length in distance along the beam. We know that V= dM/dx, and M is the bending moment. Integration yields the relationship M = M, + Vdx If Mo is zero and x 12, calculate M using a) trapezoidal rule with 1 m stepsize b) Simpson's 1/3 rule with 1 m stepsize c) Simpson's 3/8 rule with 1 m stepsize.

Question
Transcribed Image Text:1. An 11-m beam is subjected to a load, and the shear force follows the equation
V(x) = 5 + 0.25x²
where V is the shear force and x is length in distance along the beam. We know that V = dM/dx, and M
is the bending moment. Integration yields the relationship
M = M, +
Vdx
If Mo is zero and x 12, calculate M using
a) trapezoidal rule with 1 m stepsize
b) Simpson's 1/3 rule with 1 m stepsize
c) Simpson's 3/8 rule with I m stepsize.
