Solutions: shall be done in pencil on engineering paper with the following requirements: Heading: problem #, course #, date, name, sheet # Statements of given info and what is desired Sketch with dimensions Sub-headings for multi-part problems Governing equation presented without numbers - Rearrange governing equation as required Substitution of numbers into formula with unit conversions as needed Final solution, underlined, with units If placing more than one problem to a page, make sure it fits and place a thin horizontal line across the entire page between problems. Otherwise start a new page for the new problem Notes: 1) First write down what the problem is and what you are asked to calculate 2) Always determine what information you have to solve the problem and what informations you do not have and maybe you need to first obtain those needed informations The W14 x 30 is used as a structural A992 steel column that can be assumed pinned at both of its ends. Determine the largest axial force P that can be applied without causing it to buckle. (50 points) lx= 291 in4 ly= 19.6 in4 E= 29,000,000 Psi Oyield 60,000 Psi A, Cross section Area= 8.85 in Note: First Convert ft to in. 25 ft The 10-ft wooden column has the dimensions shown. Determine the critical load if the bottom is fixed and the top is pinned. Ex = 1.6(103) ksi, y = 5 ksi. 4 in. 47 2 in. (50 points) Note: First Convert ft to in. 10 ft
