Can the deflection or slope at a point on a member subjected to combinations of loadings be determined with the method of superposition method?

1) A long span open-web steel joist with a span of 70 feet is required to support a floor. The joists are spaced at 3.5 ft apart, the dead load is 15 lb/ft² (not including the self weight), the live load is 80 lb/ft? and the live load deflection is limited to L/360 (which is that used to determine the live load limit - in red/light - based on deflection in the SJI catalogue tables and those limits must be multiplied by 1.5 if L/240 is used). Using the LRFD table provided, select the most economical joist that can be used considering the self weight. The lighter values are the limiting unfactored live load. (Note: longer spans that can support the load can also be used.)

A) Calculate the stress in each link when a force of 600 lbs is applied to the rigid element AF, employing manual calculations and finite element methods. B) Determine the corresponding deflection at point A, manually applying the finite element penalty method to model and solve the constraints effectively. Available Data: The links BC and DE are made of steel. Each link has dimensions of 1/2 inch in width and 1/4 inch in thickness. Modulus of elasticity (E): 29 x 10^6 psi. Instructions: For this problem, manual calculation is crucial. Utilize the finite element method with the penalty approach to handle boundary conditions and constraints effectively. This method involves incorporating penalty factors into the system equations to enforce the constraints strictly.

A simply supported steel universal I shaped beam is shown(see attached table and choose one size) The total length is 15 meters with a concentrated force P (located at a distance a = 10 meters) created by a mass of 2000 kg. By assuming a yield strength of 350 MPa and a safety factor of 3.2 state the ergonomically suitable nominal beam size from the catalogue.  With reference to answer describe the type of beam failure and at least one possible consequence if the I-beam size you selected is too small. You may add additional images for illustration purposes but ensure that (a) it is described properly, and (b) it is relevant.
