I have plotted stress vs strain. I want to know: 1- What does the slope represent and what does it indicate? 2- How to find which material is this?
As seen in the figure, a rigid beam carried by three elastic rods of equal length from points A, B, and C is pulled to Eve from points F by P-force. The modulus of elasticity of the bars are E1=100GPa, E2=120GPa and E3=100GPa. Yield stress σA=40 MPa for bar 1 and 3, yield stress σA=120 MPa for bar number 2. Accordingly, a) determine the load PA that will start the flow, b) the load PG that will cause the migration.
Example 21.18. A solid circular steel rod 6 mm in diameter and 500 mm long is rigidly fastened to the end of a square brass bar 25 mm on a side and 400 mm long, the geometric axis of the bars lying along the same line. An axial tensile force of 5 kN is applied at each of extreme ends. Determine the elongation of assembly. For steel E = 200 GPa and for brass E₁ = 90 GPa
There is no force on a beam, but the beam is subjected to a very large temperature difference above and below. As shown in the figure below, try to calculate the vertical displacement of the midpoint of the beam, assuming that the temperature coefficient of the entire beam is a = 11.7×10^-6 °F. Tip: See Mechanics of Materials for Beam Deformation Geometry
The lower ends of the three bars in the figure are rigid homogeneous W = at the same level before the 100 kN block is attached. The temperature of the bars is then increased by 80°c. The block is assumed to remain horizontal after all deformations have occurred. The properties of the bars are shown in the table.
