The billboard sign shown weighs 4000 lb and is supported on a 15" circular hollow steel tube with 3/8" thickness. The sign will be built in west Mobile and is subjected to wind forces with maximum wind speed of 160 mph. The hollow steel tube has a maximum compressive/tensile strength of 50 Ksi and a maximum shear strength of 10 Ksi. Determine if the hollow steel tube has enough axial and shear strength to support loads applied to the sign....

A steel frame shown below is subjected to combined uniformly distributed gravity load (w 2 kips/f) and a horizontal earthquake load of H-10 kips Both the beams and the columns are made of W12x120 section having a yield strength of F 45 ksi. The Young's modulus of steel s E-29,000 ksi. The distributed load w is used to simulate the self-weight of the beam, the load transferred from roof slab, as well addition superimposed dead loads. The self-weigh...
A simply supported prismatic beam is loaded with a load applied at an angle at point F as shown below The beams connecting points CE and EF can be considered rigid (l-very large). The magnitude of the applied load P is 75kN. NOTE: You must use your student number to calculate the magnitude of the angle, α, and the length EF using the expressions below. The angle, α, is given in degrees and the unit for length EF is m...
A vertical load P = 150 kN is applied to a circular solid shaft which in turn is supported by a circular end cap as shown below. Both members are made of steel with allowable normal stress = 160 MPa, allowable shear stress 100 MPa, and allowable bearing stress 200 MPa. Determine the minimum required diameter of the solid shaft, and the minimum required outer diameter and thickness of the circular end plate. P 150 kN ds d 30 mm...

4. See the pin joint shown below, the force, pin diameter width and link thickness from the spreadsheet. Assume the link is made of steel with strength of 36,000 psi and pin shear strength of 21,600 psi. Ignore the ears. a. Is the pin in single or double shear? b. Given the force and pin dimensions, what is the shear stres:s in the pin? c. Given...
please be very 100% sure
before doing. thank you
(1) (25 points) Load-elongation dataset were obtained from a tensile test of high-strength steel as shown in the table. The test specimen had a diameter of 0.505 in. and a gage length of 2.00 in. The Poisson's ratio of high-strength steel is found to be 0.33 At fracture, the elongation between the gage marks was 0.12 in and the minimum diameter was 0.42 in 1) Plot the engineering stress-strain curve using...
