2. A cantilever beam of length 2L is loaded by a uniformly distributed load as shown below and supported at the mid-point of the beam B by a linearly elastic rotational spring with stiffness kR = 2EI/L. The relationship between the moment provides by the spring (MB) and the rotational angle at B (θB) is MB =kRθB. (25%)
3) Identify the value and location of the maximum curvature in the beam.
