- Question No. 11: (a) Illustrate flatness, straightness and circularity with symbol. (b) A circular shaft, 80 mm in diameter is welded to support by means of a circumferential fillet weld. It is subjected to a torsion moment of 3000 N-m. Determine the size of weld, if the maximum shear stress in the weld is not to exceed 70 N/mm2 . (c) Analyze different stresses during design of screw and nutarrow_forwardA steel tubing has a 1.5-in outside diameter and a 1.210-in inside diameter. It is made of AISI 1020 annealed steel having a tensile strength of 57,000 psi. What would be the safe working pressure for this tube assuming a factor of safety of 8?arrow_forwardA cylindrical air-compressor tank with an inside diameter of 50 mm is to be designed to withstand safely a working pressure of 0.86 MPa. Boiler plate with an allowable tensile stress of 76 MPa. All seams will be butt welds with an expected efficiency of 100 percent. a.) Determine the force per lineal mm of longitudinal seam, b.) Determine the required thickness “t” of wall, c.) Determine the unit stress in the circumferential seam.arrow_forward
- The figure shows a solid 2-inch diameter roller that is attached to the wall by means of a permanent clamping. Specify the weld size for the case where the maximum allowable shear stress is 18 kpsi.arrow_forwardQuestion 41. Two 10-mm-thick by 60-mm wide hot rolled SAE 1050 steel plates are to be butt-welded together with a CJP weld. Choose an appropriate electrode for tensile loading of the joint. 2. Find the torque that a 2-surface dry disk clutch can transmit if the outside and inside lining diameters are 120 mm and 70 mm, respectively, and the applied force is 10 kN. Assume uniform wear and μ = 0.4.arrow_forwardappropriate length of the weld joint shown in the figure if the force is equal to (60000lb) and the operating stress value is (60ksi) and the size of the weld is (1/4in).arrow_forward
- (1) What are the methods used to obtain a good weld when welding steel when the carbon content is high? b) Find the appropriate size and length for the weld joint shown in the figure if the strength is equal to (70000Ib) and the allowable shear stress value is 40ksi and the weld rib dimension is (1/4in)arrow_forwardA welded connection has an effective length of 150 mm. 12 mm fillet welds are used. If the ultimate strength of the weld is 485 MPa and its allowable shearing stress is 60% of Fuw. Determine the allowable shearing stress of the weld in MPa.arrow_forwardA rectangular steel plate is welded as a cantilever to a vertical column and supports a single concentrated load P. Determine the weld size if shear stress in the same is not to exceed 140 MPaarrow_forward

Two steel plates having yield point stress of 350 N/mm2 are joined together by double fillet welds of 10 mm thick as shown in figure. The weldment is from the same parent plate material. If the weld has to be replaced by 3 bolts of the same material, one each at A and B and one at mid-way between C and D, design the bolts. Take factor of safety as 2 for the boltsarrow_forward
