The bar he showed us was quite a bit narrower than 32x32cm, so if there are much stronger varieties, that pretty well fits.

- TheSpiceIsLife 4y agoFor sure, you'd likely have heard of chrom-molly steels. Got example, 4140 is a 1% chromium - molybdenum medium hardenability general purpose high tensile steel - generally supplied hardened and tempered in the tensile range of 850 - 1000 Mpa. Three to four times greater tensile strength, so two 127mm (5") diameter rods would do it at 1000 MPa.

[0] - "The wedged conductors are CD107 copper, bonded to flat Inconel 718 plates, with a 4:1 copper/reinforcement ratio over the central column area. The yield strength of the copper is 310 MPa, up to 100 °C, while the yield strength of the Inconel plates is 1130-1300 MPa. The peak Tresca stress on the Inconel at the inside radius is calculated to be 580 MPa, while that in the copper is 310 MPa."
