The First Kind of Exercise: Check the Strength of Beam Problem 1 Problem:A T-section beam with a overhang,loading and the size of its section are shown in the figure.The point C is the center of cross section and the second moment of the section is 1=2.136X107 mm4.The material of beam is cast iron whose allowable tensile stress is [o]+30MPa and allowable compressive stress is [o]-=60MPa.Check whether the beam is safe. q=50kN/m 2000 1000 20 Problem: A T-section beam with a overhang, loading and the size of its section are shown in the figure. The point C is the center of cross section and the second moment of the section is Iz=2.136×107 mm4 . The material of beam is cast iron whose allowable tensile stress is [σ] ＋ = 30MPa and allowable compressive stress is [σ]－ = 60MPa . Check whether the beam is safe.
