As a result of the load, the cylinder shortened by 0.01 in. Determine the strain. 11.2 A steel rod 2.5 mm in diameter is tested in tension. 2² The strain at the proportional limit is 0.0016. Deter- mine the deformation at the proportional limit for a gauge length 20 mm long. 11.3 An axial load is applied to a bar. The length L = 16 in. increases by 0.022 in. The width w = 3 in. decreases My TurboTax® - G... by 0.00112 in., and the thickness t = 0.75 in. decreases by 0:00 by 0.00028 in. Determine the three components of strain. 11.4 A steel cable is used on a hoist. If the maximum strain in the cable is 0.004, what is the deformation for 30 m of this cable? In Probs. 11.5 and 11.6, tabulated data from tension tests of steel are as follows. Calculate stress and the correspond- ing strain and draw a complete stress-strain curve. Draw a second stress-strain curve up to the yield point on the same graph. Determine the (a) proportional limit, (b) modulus of elasticity, (c) upper and lower yield points, (d) ultimate strength, (e) breaking strength, (f) percent reduc- tion in area (see Sec. 11.8), and (g) percent elongation (see Sec. 11.8). 11.5 For the complete stress-strain curve, scales of 1 in. = 10ksi and 1 in. = 0.05 in./in. may be used. For the stress-strain curve up to the yield point, use a scale of 1 in. = 0.0005 in./in. 11.6 For the complete stress-strain curve, scales of 10 mm = 25 MPa and 10 mm = 0.020 mm/mm may be used. For the stress-strain curve up to the yield point, use a scale of 10 mm = 0.00020 mm/mm. (Data for Prob. 11.5) Tension Test of Steel (Gauge Length = 2 in., Original Diameter=0.501 in.)
