determine the minimum square hard drawn copper rod required

determine the minimum square hard drawn copper rod required to support a 60k load? Size the rod to the nearest 1/16 inch.

Solution

>> Load to support = 60000 N

>> Ultimate Strength of hard drawn copper rod = 330 MPa

>> Size of square rod = 1/16 inch = 0.1588 cm

>> As, Load = Strength*Area

=> Area = 60000/330*10⁹ = 0.182 mm²

So, 2*pi*r*L = 0.182
