When you have completed the exam, be sure to document your work as described in the video posted earlier in our course Canvas site.  Take this moment right before submitting your exam to show your handwritten notes and work to the camera to have all opportunities to earn credit for your work. As shown in the picture below. Once you have completed all questions, documented your work in HonorLock, and submitted the exam, you will need to upload a pdf of the written work in a separate assignment. The link for this is a separate assignment in Canvas.  The file must be sent within ten (10) minutes of the time that you submit the exam.  The work will need to match what you have shown in Honorlock.  More information is available in the announcements in our course canvas site.  All the best. 

A 38-lb cardboard box sits on an oak beam. Determine the maximum bending moment in the beam if the weight is modeled as distributed load w = 1.4615 lb/in. Let a = 40 in. and b = 26 in.

A load of P = 33 N is applied a = 145 mm from the center of a 12 mm bolt. Determine the torque applied to the bolt.

A 36-lb cardboard box sits on an oak beam. Determine the maximum bending moment in the beam if the weight is modeled as distributed load w = 1.3846 lb/in. Let a = 36 in. and b = 26 in.

Determine the magnitude of the largest bending moment (consider both positive and negative peaks) in the beam. Let M = 114 lb·ft, a = 2.9 ft, and b = 8.1 ft. Assume the beam cannot lift off of the supports.

A load of P = 13 N is applied to a hex wrench that has lengths a = 40 mm and b = 136 mm. Determine the torque applied to the set screw.

A load of P = 77 N is applied a = 110 mm from the center of a 9 mm bolt. Determine the torque applied to the bolt.

A torque of T = 395 lb·in. is applied to two pulleys and a copper-alloy shaft. Determine the minimum diameter of the shaft if its shear yield strength is 25 ksi.

A torque of TC = 910 N·m is applied to the aluminum shaft. Segment (1) has a diameter of 82 mm, and segment (2) has a diameter of 41 mm. Determine the angle of twist at C. Let L1 = 0.55 m and L2 = 0.32 m.

Determine the magnitude of the largest bending moment (consider both positive and negative peaks) in the beam. Let M = 133 lb·ft, a = 2.5 ft, and b = 9.5 ft. Assume the beam cannot lift off of the supports.
