Q21. A 6-m-long vertical cantilever, a 100-mm.-nominal-diameter standard steel pipe, supports a 2400- N weight attached at the tip as shown in Fig. E6.2. the properties of the pipe are outside diameter, do = 114 mm., inside diameter d,= 102 mm., thickness t= 12 mm.), and the moment of inertia of the cross-sectional area, I = 3 X 106 mm, elastic modulus E = 200,000 MPa. Determine the peak deformation and bending stress in the cantilever due to the El Centro ground motion. Assume that = 2%. 2400 N 4 O I= 3x10 mm* -6 m- E=200,000 MPa
