A cantilever beam with a ‘T’ shaped cross-section is loaded with a distributed load as shown below.The intensity of the distributed load is 100N/mm. b = 6.25mm and c=6.25mm.Parameter Description Value UnitsL - Beam length 250 mma - Width of the flange 80 mmd - Height of the web 75 mmσ - Yield stress 250 MPaYou are tasked with ensuring the beam can withstand the applied loading. To do this you must:a) Calculate the centroid for the given cross-section. Your value of ?ത should be measured fromthe bottom of the section. Determine an expression for Q (statical moment of area) for thegiven shape. The expression(s) for Q should be in terms of the variable, y, measured from thebottom of the section. b) Create a graph of the shear and bending stresses at the fixed support (B) over the crosssection. The stresses should be plotted as a function of y, measured from the bottom of thesection.

Compute for the maximum allowable distributed load o that can be applied to the simply supported beam as shown in Figure M-Va. The beam's cross section is detailed in Figure M-Vb. @(N/m) Allowable Stresses: Fiber Stress = +13.5 MPa / -12 MPa Transverse Shear Stress at NA = 900 kPa Transverse Shear Stress at Junction 800 2 m Figure M-Va 2 m Draw the flexural and shear stress distributions of the cross section.

The beam shown below with a length L = 20 m and a rectangular cross section that has a width of b = 50 mm and a depth d = 150 mm, has a load applied a x = 3 m away from the left hand support.  What is the maximum load P that can be applied on the beam if the maximum bending stress can't exceed 14.0 MPa.  Ignore any load factors or strength reduction factors.

Consider the beam below. If the beam is subject to a 20kN internal shear force, determine the maximum shear stress (in MPa) in the beam. The thickness of all pieces is 30mm.
