Problem 4: Two wooden members shown which support a 4.5kip load, are joined by plywood splices fully glued on the surfaces in contact. The ultimate shearing stress in the glue is 360psi and the clearance between members is 1/4in. Determine the required length L of each splice if a factor of safety of 2.75 is to be achieved. 4.5kips

The data in Table 1.5.3 were obtained from a tensile test of a metal specimen with a rectangular cross section of 0.2011in.2 in area and a gage length (the length over which the elongation is measured) of 2.000 inches. The specimen was not loaded to failure. a. Generate a table of stress and strain values. b. Plot these values and draw a best-fit line to obtain a stress-strain curve. c. Determine the modulus of elasticity from the slope of the linear portion of the curve. d. Estimate the value of the proportional limit. e. Use the 0.2 offset method to determine the yield stress.
