1.) What is the value of the bending moment (kN m) that will cause the beam to crack? 2.) Determine the bending stress (MPa) in the extreme fiber in compression due to the cracking moment? 3.) In addition to its own weight, what uniformly distributed load (kN/m) can the beam safely carry before it cracks?
Extracted text: A perforated T- beam has the following properties: br = 550 mm bw = 270 mm tr = 100 mm h = 600 mm Ye = 24 kN/m F: = 2.8 MPa (Tensile Strength) A 120 mm Ø hole, center at 550 mm above the bottom of the beam, is allowed for the passage of pipes. bw
