2.7-P: Problem Set

Suggested Problems

For each of the following frames:

  • compute all reactions and show on a summary FBD of the whole structure.
  • draw complete FBDs of each structural member, showing numeric values for all important internal forces.
  • determine the internal member forces at the locations marked (with an ‘*’) and show that joint equilibrium is satisfied.
