So the right rod would just move down 31δ/39 and the left 15δ/39? I still am unsure of where to go from here. The sum of the forces for each rod (F1 and F2) I presume would equal the 8000 lbs. When F1+F2=8000 is expanded you have the unknowns of the initial length L (from ε=ΔL/L) which is the...
Homework Statement
A rigid weightless horizontal beam is hinged at a wall and is supported by two rods. The beam has a 8000 pound load applied at the end. Calculate the tension in each rod. The left rod is made of brass and has diameter of 1.25" and the right rod is made of aluminum and has a...
