Types of loading

In mechanical terminology, the term load indicates that external force/weight, either constant or variable, acts on a mechanical member/structure. The weight of an object of a specific material is also an external load, and the external force that works on a structure comes under the categories of loading. The external load generates its effects as stress and strain in the structure.

**Problem Statement:**

For the truss structure shown, use symmetry to determine the displacements of the nodes and the stresses in each element. All elements have \( E = 30 \times 10^6 \) psi. Elements 1, 2, 4, and 5 have \( A = 10 \, \text{in}^2 \) and element 3 has \( A = 20 \, \text{in}^2 \).

**Diagram:**

- A symmetrical truss with five elements is illustrated.
- Nodes are labeled at the top and ends of each truss element.
- Element 3 is vertical, connecting the apex node (3) with the base.
- All other elements (1, 2, 4, 5) are diagonal or horizontal, meeting at the apex node from the base.
- The base of the truss spans 16 feet in total, with individual 8-foot sections on each side.
- The height of the truss (from the base to the apex, node 3) is 6 feet.
- A downward external load of 20,000 lbs is applied at the apex node (3).
- Supports are located at node positions 1 and 4, one being a pinned support and the other a roller support.

Jeff was just hired by GSI, Inc. to be their Environmental and Safety Coordinator. This is Jeff's first position after completing his engineering degree. He had taken a course in safety engineering as part of his studies and felt confident that he could handle the job. Management at GSI, Inc. has assured him that they are committed to maintaining a safe workplace. They have never had an individual dedicated to this task full-time. They will implement his recommendations if he can justify them. As Jeff begins to get familiar with the operations, he spends considerable time on the production floor. He notices workers clean their tools before break with a liquid from an unmarked 55-gallon drum. They also use this liquid to clean residue from their skin. They use paper towels to dry their tools and hands, throw these towels in the trash, and head to the break room for a snack and/or smoke. In talking with the workers, Jeff learns of some of their concerns. Several people mention…
Good morning interns, This is Ms. Gorman from the sales department. We have just secured a new, multi-million-dollar account! We are so good here in the sales department of Heavy-Duty Box Inc. The manufacturing director, Mr. Tsosie, has instructed me to send this problem out to all of you as this will be a deciding factor in which of you get offered the full-time positions available at the end of the internship! Our new client, Beastie Bearings Inc., needs the heaviest duty box we make here at Heavy-Duty Box for their bearings. The following email from Ms. Venegas from Beastie Bearings provides the information you will need. Remember, our mark-up sales price is 150% of what it costs us to manufacture the product. The cheaper it is for us to produce the box, the lower the cost for our client. There is also a grading rubric attached that Mr. Tsosie will be utilizing in evaluating your work. I would advise you to follow it well if you want a position! Good luck interns, Ms. Frances…
