Metal sheet Definition and 13 Threads

[Mentor Note: Thread created by moving some posts from a previous thread into this new one by the OP.] if I have 1)10X10 cm box 2) weight 300g 3) The dimensions of the surface sheet that will be in contact is 60x25 cm 4) should be flat with holes for the air 5) that surface either can be an...

I calculated FS Model using Mathcad and I got that this part increases with decreasing width $\w$. This make the resistivity increases with decreasing width $\w$. This contradict the result of this model. Has anyone ever come across with this before? the original paper...

Homework Statement Stretch forming[/B] A 38.1 cm-long sheet with a cross sectional area of 3.2258 cm2 is stretched with a force, F, until alpha = 0.35 rad. The tip of the force is fixed to the strip by some means, thus maintaining the lateral position of the force. (The left portion of the...

Homework Statement A punch is used for cutting an (approximately) circular hole with a diameter of 35 mm through a metal sheet 0.2 cm thick. If the shear strength of the metal is 80 MPa, estimate the force needed to punch the hole. Make it clear how you have calculated this value. Homework...

Hello. I'm using CT (Current Transformer) to measure the current flowing on the power line. The frequency of the current is 13.56 MHz. CT appeared to be metal-shielded (This metal case of CT may be grounded when CT is used). CT has a toroidal shape and the power line under the measurement...

Homework Statement How much work would be required to remove a metal sheet from between the plates of a capacitor, assuming a) the battery remains connected so the voltage remains constant b) the battery is disconnected so the charge remains constantHomework Equations When a metal sheet with...

Dear Friends, Merry Christmas to All. I am pleased to join this forum of Physics Experts. Please advise what is difference between tensile Strength and Bending Stress of Metal Sheets (Generally below 3.00mm and lighter). I very often encounter with cracking of steel sheets while bending in...

Hi everyone, I have been trying to find an equation to measure the length of a coil. The coil is a metal sheet that wraps around the loops as it creates. It looks like a roll of tape. I have been using two different formula, but it is not giving me the right results. 1. L = 0.065449 (OD^2 -...

Homework Statement There are two big, same size, uncharged metal sheets in the same plane, lying parallel and very close to each other. The sheets are connected through a piece of wire, and then a pointlike charge Q is placed next to them as shown in the figure. What will the amount of charge...

Why does a metal sheet between two wires not have a shielding effect on the magnetic field? Considering the magnetic force can be explained as the electric field in a different frame. With wires changing frames is a little complicated, but take this simplified situation. In the lab frame...

I am working on a project, all details can be found http://www.overclockers.com/forums/showthread.php?t=680115" is the catalog page with the options. I've googled about annealed and "dead soft" however I still can't tell exactly how soft/flexible it is. All I need it to support is water running...

Homework Statement A thin square (4 ft side) metal sheet of homogeneous density (\sigma = M/Ais rotating around one of its diagonals at 10 rev/s. Develop a definite integral to express its kinetic energy. Homework Equations dK = \frac{1}{2}(r\omega)^{2}\sigma dA The Attempt at a...

Homework Statement "A manufacturer of corrugated metal wants to produce metal roofing panels that are 28 in. wide and 2 in. thick by processing flat metal sheets." the illustration shows that by "2 in. thick" they are referring to the distance between the crest and valley of the sine wave...
