Homework Statement
You have to design a rod to hold up the hood of your car. Assume the hood weighs 40 lbs, and the rod must be 3 feet long.
What material would you use to make the rod? And what diameter would you make the rod?
Homework Equations
Stress= Force/Area
Buckling equation for member pinned at both ends
The Attempt at a Solution
1) use yield strength of chosen material in stress formula, and solve for area, and therefore diameter.
2) verify that the solved rod diameter will not buckle under given load
Could you please clarify:
-is the yield strength in compression the same as in tension?
-should a safety factor be applied? Is it worth considering for such a low-risk application?
