Given a shearing force V of 150kN:
-Determine the maximum, minimum and average shearing stresses in
the vertical web of the I-type cross section. Compare the
magnitudes of these shear stresses. What is your conclusion? (Note:
the average shear stress in the web is the shear force/area of the
web)
-Determine the shear stress in the flange at a distance of 95mm
from the tip (point X).

Question 4: Shear stress in a beam (40 marks)
Consider the beam section illustrated in the figure to the
right. The beam has a shearing force of V = 5 kN acting vertically
through the shear center as illustrated. (a) Determine the shear
stress at the three points in the beam section labelled (i), (ii),
and (iii). [20 marks] (b) Produce a plot showing the direction and
distribution of shear stress across the beam section, noting the
shape of the...

Learning Goal: To calculate the shear stress at the web/flange joint in a beam and use that stress to calculate the required nail spacing to make a built- up beam. A built up beam can be constructed by fastening flat plates together. When an l-beam is subjected to a shear load, internal shear stress is developed at every cross section, with longitudinal shear stress balancing transverse shear stress. If the beam is built up using plates, the fasteners used must...

Review An engineered wood beam (Figure 1) will replace a portion of a structural wall as part of a house renovation. The beam can be modeled as a simply supported beam with a span L = 18 ft and an uniform distributed load w = 810 lb/ft . The beam is to be constructed as an I-beam with nails securing the flanges to the web. The flanges are 6 in wide and 1 in thick. The web has depth 18...

How
do I solve this?
Problem 2(50 points) The roof of the Edwin A. Stevens building is to be redesigned to accommodate a billboard for Stevens Institute of Technology. The new billboard will weigh 40 kips and be supported equally by two columns located 9 ft from the rear of the building. The beams supporting the new roof will be simply supported as shown. (Note there is a 5 ft overhang at the front of the building). For the grade...
