Resistance projection welding is used to simultaneously weld two thin, steel plates together at four locations. One of the pieces of steel plate is preformed with projections that have a diameter of 0.25 in and a height of 0.20 in. The duration of current flow during the weld is 0.30 sec and all four projections are welded simultaneously. The plate steel has a unit melting energy of 140 Btu/in3 and a resistance between plates of 90.0 micro-V. Experience has shown that 55% of the heat is dissipated by the metal and 45% melts the weld nugget. Assume the volume of the nuggets will be twice the volume of the projections because metal from both plates is melted. How much current is required for the process?

Linear loop array. An antenna array is made of n loops, all lying flat on a surface in a line, separated a distance 2d apart where d = 0.02λis the diameter of the loop.
A helical compression spring made from hard drawn wire needs to be designed to fit inside a 50mm cylindrical cavity and there must be enough space inside the coils for a 20mm cylindrical guide rod.
A belt moves upward at velocity V, dragging a film of viscous liquid of thickness h, as in Fig. C4.2. Near the belt, the film moves upward due to no slip.
If the length of each spring is 120 mm when the radius of the spring is 70 mm and the equilibrium speed is 360 r.p.m, find the free length of the spring. If the radius of the rotation increases to 120 mm, what will be the corresponding percentage ..
