Midterm Exam
ES 202 – Statics of Rigid Bodies
This is the questionnaire part of this midterm exam. Go over the numbered questions and take
note of your answers by writing them in a sheet of paper. Once you are done with this
questionnaire open the answer sheet still found in the classwork and tick the circle in a number
that corresponds to the best answer. Points to be earned for a question is indicated below each
question and the highest possible score will be 90 points.
Multiple choice: Choose the letter that corresponds to the best answer.
