# 1 The Base Of Machine Is Supported By Four 4 Two 2 Leg Supports Like A Shipping Cont 3951371

1. The base of machine is supported by four (4) two (2) leg supports (like a shipping container crane) consisting of 2.4m long steel struts pinned at each end. The machine must remain level and aligned at all times. Due to a maintenance issue, one of the 20mm square struts is replaced with a 20mmx50mm titanium one.

2. A 500ft length of 3/4”-6×37 class bright wire rope EIPS IWRC (steel cable) is to be used to suspend some lights across a football field. It is attached to adjustable eye bolts at each support. Each eye bolt has 12 inches of adjustment available. The bolts are exactly 500 ft apart to start.

2a. How far do you need to loosen the eye bolts to initially hang just the cable? (Note: it may help to treat the distributed load as a point load at the middle with the cable acting as two thin rods initially 250 ft long)

2b. What is the final position of the bolts in order to have the cable “sag” less than or equal to 6 inches after the light) is attached?

3. A steel process component is mad by welding three (3) pipes to two (2) pre drilled steel end plates. Due to a serious lack of caffeine, the center pipe is cut 0.35mm short. The worker decides to fix the problem by forcing the ends together in a large vice and then welding the center pipe (B).

3a. What is the stress in each pipe after it is removed from the vice? (Neglect any welding stress)

Note that triangle thing (all connections) on C is a welding symbol for a 6mm fillet.

3b. Discuss/explain what this did to the capacity of the finished part.
