A machine member 50 cm. long, of inverted T-section, shown, (thickness a, width 6a, height 6a) is subjected to a 0 to 10 MT (metric tons). The variable, axial, repeated compression load from material is 4130, WQT, 1100F (Sy = 800 MPa, E = 210,000 MPa). Calculate the dimensions of the cross-section, a, b, c, considering: a. simple stress, with N=2 on Sy b. buckling only(decide whether Eulers or Jonnsons column and use N = 3.5, Let Le = 2L) c. varying stress. Let Kf = 1.5, S-400 MPa, indefinite life, other factors as unity.
