CVEN 345-501/502 Final Examination 120 min SPRING 2023 Name: Date: Practice Exam 1 /15 2 /25 3 /30 4 /30 Total /100 Directions: Show all your work as required for each problem including any sketches that might be needed to arrive at your final answer. Partial credit will only be awarded if your process is clearly understood. Having the correct answer but indecipherable process will receive minimal credit. Note: Any statics/dynamics equation you write must be clearly linked to a well-drawn free-body diagram you have drawn. If that is not the case, I will disregard the equation and grade your solution as if you had never written it. Use a straight edge for your drawings! ______________________________________________________________________________ I pledge that I have neither given nor received aid in completing this exam.
