Mechanical deformation question

AI Thread Summary
The user is attempting to calculate mechanical deformation using the formula δ = NL/AE, with values for N, L, A, and E. They found E to be 15 KSI and calculated a deformation of 25 inches, but the expected answer is 0.025 inches. A suggestion was made to recheck the value of E, implying a potential error in the unit conversion or value used. Additionally, there was a reminder to post such queries in the homework section in the future. The discussion highlights the importance of accurate unit conversion in mechanical calculations.

I know that i should use the equation:
δ = NL/AE
In this case, i looked up E and found it to be 15 KSI.

Im trying to find the change in distance between points B and C. Therefore, N should be 2 kips (2000 pounds), L is 150 inches, and A in 0.8 inches squared. Plugging this into the equation gives me 25 inches. However, the correct answer is 0.025 inches.

I think I'm close, but somewhere I'm going wrong. Any help would be great.

I think you slipped a few zero's when you looked up the value for E. Check it again. In the future, please post in the homework section . Thanks.

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
