Calculate Steel Plate Thickness

Job ID: 34541572

Budget: £10 – £20 GBP

A circular plate which is supported via the centre lifting eye, will carry a load of 7.5 ton (7500kg) via the outer PCD of holes which have a PCD of ∅300mm. It can be assumed that the 7.5 ton load will be evenly distributed at the ∅300mm circumference. (See diagram on page 2)
We require a calculation to determine the required thickness of the steel plate. We also require four calculations for the 4 variables. NOTE: Please provide all methods and proofs of calculations.
