Determine the properties of the double angle shown in the Figure 1 . The section is made of 2 L 125 x 75 x 10 with long legs back-to-back and spacing s = 5.60

A simple beam AB is loaded as shown in the figure. A В L L L 4 4 4 4 (a) Calculate the required section modulus S (in in.³) if oallow 18,000 psi, L = 15 ft, P = 3,250 lb, and q = 450 lb/ft. (At this point, disregard the weight of the beam.) 0.85286 X in. 3 Select a suitable I-beam (S shape) from this table, and recalculate S (in in.3), taking into account the weight of the beam. Select a new beam size if necessary. (Select the most economical beam size for your calculations.) 1.000 in. 3 What is the suitable beam size? O S6x 12.5 O S6x 17.2 O S 8× 23 O S 10 x 25.4 OS 8× 18.4 (b) What is the maximum load P that can be applied to your final beam selection in part (a)? (Enter the magnitude in Ib.) 3221 X Ib

The simply supported wood beam is loaded as shown.  Ewood=10 GPa What is the slope at A? What is the deflection at C?

The force of an L-shaped round bar is shown in the figure below. Assuming that bending moment, torque and shear force effects need to be considered, try to calculate the vertical displacement of point C. E of the entire section is 200 GPa, G is 75 GPa, I, J The calculation with A assumes that the radius of the rod is 30 mm.
