Determine the fillet weld size needed between the bracket and the support for a static load of P = 12 kN.

1.       Figure P16-1 shows a bar welded to a base with 3/16 in fillet welds on three sides using an E70 electrode. Material is A572 Grade 50 hot-rolled steel. What is your recommended maximum dynamic repeated load, zero to Pmax that can be applied for 10E8 cycles with a safety factor of 1.6?

2.       Figure P16-2 shows a bracket welded to a wall with a fillet weld using an E70 electrode. For the row(s) assigned in Table P16-1, determine the fillet weld size needed between the tube and wall for a static load and = 1.2OD= 2OD, and = 2.5OD. The pipe and wall material are A36 steel.

1.       Figure P16-3 shows a bracket machined from 12-mm-thick A572 Grade 50 hot-rolled steel flat stock. It is welded to a support with a fillet weld all around using an E80 electrode. Determine the fillet weld size needed between the bracket and the support for a static load of = 12 kN.

2.       Figure P16-3 shows a bracket machined from 12-mm-thick A572 Grade 50 hot-rolled steel flat stock. It is welded to a support with a fillet weld all around using an E90 electrode. Determine the fillet weld size needed between the bracket and the support fora dynamic load that varies from 0 to +3 kN using a safety factor of 1.8.
