2. A helical compression spring is made from No. 8 steel wire and is to carry a 100 lb static load at a deflection of 1 inch. The outside coil diameter of the spring is 0.972 inches. The spring ends are squared. Assume the torsional yield strength of the wire is 80000 psi, and the shear modulus is 11.4 Mpsi, determine (a) The static load corresponding to the yield strength. (b) The deflection that would be caused by the load...
please be very 100% sure
before doing. thank you
(1) (25 points) Load-elongation dataset were obtained from a tensile test of high-strength steel as shown in the table. The test specimen had a diameter of 0.505 in. and a gage length of 2.00 in. The Poisson's ratio of high-strength steel is found to be 0.33 At fracture, the elongation between the gage marks was 0.12 in and the minimum diameter was 0.42 in 1) Plot the engineering stress-strain curve using...

1. During a stress-strain test, the unit deformation at a stress of 5,000 psi was observed to be 0.000167 in./in. and at a stress of 20,000 psi it was 0.000667 in./in. If the proportional limit is 30,000 psi, what is the modulus of elasticity? What is the stress corresponding to a strain of 0.0002 in./in.? Would these results be valid if the proportional limit were 18,000 psi? Explain. 2. A steel wire 30 feet long, hanging vertically, supports...
