- A tension plate shown below is used to support suspended load "T". Gusset Plate F, = 248 MPa Fu = 400 MPa 200 mm. Determine the allowable tensile capacity of the plate if L= 240 mm. (Assume weld strength is satisfactory)A U-groove weld is used to butt weld 2 pieces of 7.0-mm-thick titanium plate. The U-groove is prepared using a milling cutter so the radius of the groove is 3.0 mm. During welding, the penetration of the weld causes an additional 1.5 mm of material to be melted. The final cross-sectional area of the weld can be approximated by a semicircle with a radius of 4.5 mm. The length of the weld is 200 mm. The melting factor of the setup is 0.57 and the heat transfer factor is 0.86. (a) What is the quantity of heat (in Joules) required to melt the volume of metal in this weld (filler metal plus base metal)? Assume the resulting top surface of the weld bead is flush with the top surface of the plates. (b) What is the required heat generated at the welding source?The allowable unit stress in shear on a fillet weld is 13,600 psi, and the total actual length of the weld cannot exceed 3 in. If the weld must transmit a total force equal to 9600 lb, it’s size should be A. 1/2 in. B. 3/8 in. C. 5/16 in. D. 1/4 in.

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 nutA 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 MPaA bracket, as shown in figure below, is welded to a plate. The welds have the same size, and thepermissible force per mm of the weld-length is 1 kN. Calculate the lengths l1 and l2.
- Question: a) A plate 100 mm wide and 10 mm thick is to be welded to another plate by means of double parallel fillets. The plates are subjected to a static load of 80 kN. Find the length of weld if the permissible shear stress in the weld does not exceed 55MPa. Determine the increase in load carrying capacity if a combination of single transverse double parallel fillet is used the permissible tensile strength of material is 80MPa. b) Draw a neat sketch of double riveted double cover but joint. If 8mm plates with 20 mm diameter rivets having a pitch of 50 mm are joint using double riveted lap joint. The permissible stresses are permissible tensile stress = 120 MPa;Permissible crushing stress= 100 MPa; Permissble shear stess= 150 MPa. Find the strengths and efficiency of joint, taking the strength of the rivet in double shear acoording to the indian boiler standards.A 1/4 in fillet weld is to transmit a total force of 12,000 lb.

The lap welding tensile strength is 450 MPa and the weld -joint efficiency is assumed to be 100%. Compute the bursting pressure of the receiver in kN/m².QUESTION 20 Below is an image showing two 4 mm thick sheets joint together using double rivets. If the rivets were made of stI need right solution with clear calculations. 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 bolts
