Problema 1 A steel column has a length of 9 m and is pinned at its top and bottom. If the cross-sectional area has the dimensions shown, determine the critical load. $E_{st}$ = 200 GPa, $\sigma_y$ = 250 MPa. 200 mm 10 mm 10 mm 150 mm 10 mm Problema 2 The A992 steel angle has a cross-sectional area of A = 2.48 $in^2$ and a radius of gyration about the x axis of $r_x$ = 1.26 in. and about the y axis of $r_y$ = 0.879 in. The smallest radius of gyration occurs about the a-a axis and is $r_a$ = 0.644 in. If the angle is to be used as a pin-connected 10-ft-long column, determine the largest axial load that can be applied through its centroid C without causing it to buckle. Problema 3 Determine the critical load of a pin-ended steel tube that is 5 m long and has a 100-mm outer diameter and a 16-mm wall thickness. Use E = 200 GPa. 16 mm 100 mm

3. Draw two different mechanisms to account for the following transformation under acidic conditions + R'—N—R' + catalytic H$^+$ NR'$_2$ + R O || C R Me H O || C H R'' R R'' There are two well-differentiated mechanistic pathways that lead from starting materials to product. These two mechanisms differ in the sequence of assembly of the starting materials. Draw both of these mechanisms.
