1.Two wooden members joined by a simple scarf splice and its diagram. The maximum allowable tensile stress in the splice is 75 psi. Determine the largest load P that can be supported and the corresponding shearing stress in the splice.
2.The mean annual precipitation for a certain 132 square mile watershed is 25 inches. Assume the 20 percent of the annual precipitation reaches the watershed outlet as stream flow. Determine the mean stream flow rate in ac-ft/yr, sfd/yr, and square meter/second
