A 30mm diameter bar is 1.25 m long. When the bar is simply supported at its ends in a horizontal position and is loaded with a concentrated load of 370 N at mid span, the central deflection was found to be 9.50 mm. In the second case, the bar is placed vertically and loaded axiallyThe buckling stress (in N/ mm²) of the vertical bar is

The beam has a Young's modulus of Eo 100 GPa, a length of / = 4 m and 2nd moment of area of I₂ = 4 m². The intensity of the uniformly distributed load is w = 100 N/m. Now calculate the maximum beam deflection: Umax = X Expected answer: 0.1149623254 (m)

A steel beam is 24 inches tall, has a length, L, of 32ft, and has a yield stress of 36ksi. The simply supported beam supports a single load, P, of 17 kips at its midspan. If the theoretical maximum deflection of this beam is -(PL^3)/(48EI), determine the required moment of inertia such that the actual deflection of the beam will not exceed a value of L/360, and the actual stress will have a factor safety of 1.5 with respect to yielding.
