Example 3: The beam shown below has a cross section of channel shape with width b-300 mm and height h=80 mm, the web thickness is t=12 mm. Determine the maximum tensile and compressive stresses in the beam due to uniform load. 300mm 3.2 KN / m 80 mm -12mm B 3m 1.5 m

The steel beam has the cross section shown. The beam length is L = 4.2 m, and the cross-sectional dimensions are d = 360 mm, bf = 180 mm, tf = 16 mm, and tw = 6 mm. Calculate the largest intensity of distributed load w0 that can be supported by this beam if the allowable bending stress is 210 MPa.

A wooden frame shown below is supported by a tie rod CF and a pin support at A. The diameter of the tie rod CF is 30 mm, and the cross-sectional area of member BD is 900 mm?. The diameters of the pins at A and D are 8 mm and 12 mm, respectively, and each pin is subjected to double shear. If the weight of the bucket hanging from end E is 3 kN, determine (a) The axial stresses in tie rod CF and member BD. (b) The shear stresses in pins A and D. - 0.6 m-0.6 m→ D E 0.6 m V30B 1.2 m F

02: The rigid platform has negligible mass and rests on two steel bars, each 250.00 mm long. The center bar is aluminum and 249.90 mm long. Compute the stress in the aluminum bar after the center load P= 400 kN has been applied. For each steel bar, the area is 1200 mm2 and E= 200 GPa. For the aluminum bar, the area is 2400 mm2 and E 70 GPa Rigid platform Steel Ahmum Steel
