Shear of Thin-Walled Beams (closed section) 3. A box girder has the singly symmetrical trapezoidal cross...
5.4. A thin walled box section has two compart- ments as shown in Figure 5.26. The thickness of the section is constant. What is the shear stress in both the cells? Take a10 cm,8 mm. What will be the angular twist per unit length if G= 80 kN/mm"? Torque applied on shaft is 400 Nm. a Figure 5.26 Problem 5.4
The cross-section of a thin walled single cell tube is shown in Figure 1 below. The tube supports a torque of T-3 kN.m over a length of 8 m. Consider G of the material as 79 GPa. 1. Determine the shear stresses in the walls and angle of twist 2. A vertical web of wall thickness of 2mm is added in the single cell to make it a two cell tube shown in Figure 2 below. Also determine the shear...
A steel tube with a circular cross section has an outside diameter of 300 mm and wall thickness of 2 mm. The cylinder is twisted along its length of 2 m with a torque of 50 kN · m. (a) Determine the maximum torsional shear stress using Equation Theta= T*L/JG (b) Determine the maximum torsional shear stress using the closed thin-walled tube method. Compare this result to the result of part (a). (c) Assuming the tube does not yield, determine...
The hollow thin-walled hollow section of aluminium alloy illustrated below is 1200 mm long. It has one free end and the other is built into a solid wall. At the free end, the following loads are applied in the directions illustrated and distributed evenly over the perimeter of the section:- A central, axial compressive load, P = 10 kN; and A torque, T = 0.2 kN.m. Properties of the aluminium alloy are given as E = 72 GPa and =...
