- The Normal Strain In A Suspended Bar Of Material Of Varying Cross Section Due To Its Own Weight Is Given By The Expressi 1 (28.95 KiB) Viewed 32 times
The normal strain in a suspended bar of material of varying cross section due to its own weight is given by the expression γy/3E where y=2.3lb/in33 is the specific weight of the material, y=4.4in. is the distance from the free (i.e., bottom) end of the bar, L=22in. is the length of the bar, and E=29000ksi is a material constant. Determine, (a) the change in length of the bar due to its own weight. (b) the average normal strain over the length L of the bar (c) the maximum normal strain in the bar. Answer: (a) δ= ×10−6 in. (b) εavg= με (c) εmax= με
