Problem 14.3.A A 4 × 4 x 2-in. angle of A36 steel is to be welded to a plate with E 70 XX electrodes to develop the full tensile strength of the angle. Using %-in. fillet welds, compute the design lengths for the welds on the two sides of the angle, assuming development of tension on the full cross sec- tion of the angle. A=3.75 inch2 L1= 10.94" L2 = 5.09" IF only connected leg, L=7.7"; 4.75 each side
8. Design the length of weld (L) in the connection below to develop the full tensile capacity of the plate. Use E70 electrodes and 1/4" side fillet welds. The material is ASTM A36 Steel and the allowable axial tensile stress is 22,000 psi. (show all your work) "L" PL 1/2" PL 3/8" x 6" P
3.) The diagram below shows a 5.5m long double angle brace which is connected by 6mm welding connection. The length of weld shown in the picture is 300 mm on the top and 100 mm on the bottom. The 2-L127x 89x6.4 are 300W steel and long leg back-to-back. The braces are to be welded to a 12 mm 350W steel gusset plate. Determine the factored tensile capacity of the angles. Any intermediate connections that are required should also be specified. 740 kN -12 mm Gusset Plate
QUESTION 3 2. For the given welded bracket shown, design the required size of weld needed to resist the given eccentric load P=125 kN. Use E70xx electrode. Where: X=150mm, Y=125mm, Z=50mm what is the maximum force on the welds in kN? (2 decimal places) X Y
Using SMAW process, E70 electrodes and an A572 steel. Determine the length of the side fillet welds for the full capacity the 125x100x10mm angle tension member as shown below. Assume that the member is subjected to repeated stress variations making any connection eccentricity undesirable. Check the block shear strength of the member. Assume that the WT chord has sufficient strength to develop the weld strengths and the thickness of its web is 12mm. Use U = 0.87 for class use and LRFD Method only

11.16 Two 20-mm steel plates are butt-welded together. Both the plate and the welding electrode materials correspond to strength properties of Su = 500 MPa and S, = 400 MPa. The imposed loading fluctuates rapidly between -20 and +60 kN. Estimate the length of weld required in order to provide a safety factor of 2.5: (a) If the weld reinforcement is not removed. (b) If the excess weld material is carefully ground off to provide smooth, continu- ous surfaces.
