airjordan223 Posted October 17, 2008 Share Posted October 17, 2008 three prismatic bars, two of material A and one of material B transmit a tensile load P. the two outer bars are identical. the cross sectional area of the middle bar is 50% larger than the cross sectional area of one of the outer bars. also the modulus of elasticity of material A is twice that of material B a) what fraction of the load P is transmitted by the middle bar b) what is the ratio of the stress in the middle bar to the stress in the outer bars c) what is the ratio of strain in the middle bar to the strain in the outer bars.

DelSolSweetie Posted January 26, 2009 Share Posted January 26, 2009 ^ 2 maybe? im in diff eq. and never even understood that basic stuff haha this is my question in physics: "the potential energies associated with four orientations of an electric field dipole in an electric field are.... etc.. rank the orientation according to the angle between the electric dipole moment p and the electric field E and the magnitude of the torque on the electric dipole, greatest first." i hate physics and calculus Link to comment Share on other sites More sharing options...

I've got an 8 page paper due sometime next month about the effects of ionizing radiation on human beings..I plan to do my subject on the experimental radiation testing on humans in the 50's.
