Problem 4. Your boss has asked you to order a steel pipe to be used as...
As shown, a pipe serves as a short column. The 4 - inch diameter steel pipe has 6 in x 6 in in steel plates welded to its ends.The top column plate carries a 5-1/8" wide wood beam that exerts an axial load on the column of 11,800 lbs., including the weight of the beam. The bottom plate bears on a concrete pad. The weight of the column is 53.5 lbs. Compressive stress in the steel must not exceed 20,000...
The column shown is made by filling a steel pipe with concrete. The concrete has an Elastic Modulus of Ec-3.800ks1 and a cross-sectional area of Ac-80 in2 the steel pipe has an Elastic Modulus of Est 29,000 ksi and a cross- sectional area of Ag-11 in2. If the column has a length of L = 10 ft and is subjected to a load of P 280 kip, what is the stress in the concrete? Express your answer in psi, to...
Complefe the following: problem Parameters/notes Change the load: Dead -10 psf. Live - 30 psf hint: first trace the load W to the ends of the rods, then draw a FBD of the beam and rod and solve for reactions at C and B. Use this info to find the force in the rod. Your answer should be the diameter of a round rod rounded to 1/8" increment). Change the load to 400,000 Ibs See Appendix table A3 for Steel...
Chapter 5, Reserve Problem 078 A steel [E = 29,100 ksi; a =6.4 x 10-6/0F] pipe column (1) with a cross-sectional area of A4 = 5.20 in.2 is connected at flange B to an aluminum alloy [E = 10,200 ksi; a =12.8 x 10-6/0F] pipe (2) with a cross-sectional area of Az = 4.10 in.2. The assembly (shown in the figure) is connected to rigid supports at A and C. It is initially unstressed at a temperature of 93°F. Assume...
Problem (3): Given: A 24"X24" column has been designed using the following diagram. The axial load on the column is Pn-1,200 kips, and the steel ratio is p-0.03.

12 Section 4. Problem 12 (25 pts.) A cylindrical pressure vessel is constructed by welding steel plates together. The pressure vessel supports an internal pressure of 250 (psi). In addition the pressure vessel supports an axial load of 230000 (lbs.). The inner radius of the pressure vessel is 56 (inches) with a wall thickness of 0.4375 (inches). The plates are welded at 57 degrees from the horizontal. Determine: a) the stresses perpendicular and parallel to the weld. Show the stresses...
Please answer in numerical order.
1. Use ρ-p0.004 and choose (you decide) the number (3 to 5) and size of steel bars from the attached table. Then proceed to determine (a) the size of the cross-sectional area, (b) the moment capacity of the RC section that you design, and (c) show where is the neutral axis on the diagram (or sketch a new one). 2.5" Given: fe 3,000 psi, fy -60,000 psi Concrete cracking strain 0.003 Initial yielding strain of...
Problem 3. Assume that the house is 9 feet tall, has pipe size of 20 in. and post height is 40 ft. See the chart below for the cross-sectional properties of your pipe. Assume a wind pressure of 30 psf. a. Calculate the force/foot of pipe by multiplying the wind pressure by the diameter of the pipe. The uniform load is 1200 on the pipe in lb/ft. b. Calculate the resultant force caused by the wind on the house. Treat...
