Thank you very much PhanthomJay, your help is much appreciated!

Hi again PhanthomJay, the question is this: "A mild steel column has a cross section of 100mm by 50mm. Assuming a safety factor of 6 calculate the load that it can safely support." So with this in mind, the length is not stated. So assuming buckling is not required in the answer to this...

Hi PhanthomJay, Thanks for your reply. Considering your advice, is it as simple as follows then: P = AσK Where: P is safe working load - ? A is sectional area - 100mm x 50mm = 5000mm2 σ is ultimate strength of material (mild steel) - 480N/mm2 K is fraction - 1/6 or 0.167...

Homework Statement A mild steel column has a cross section of 100mm by 50mm. Assuming a safety factor of 6 calculate the load that it can safely support. Homework Equations Column material: mild steel Column cross section: 100mm x 50mm Safety factor: 6 On the basis that the...

Homework Statement A beam has a solid square cross section of 100mm and is simply supported by two supports 3m apart. Calculate the dead load that can be safely supported when applied to the middle of the beam. Homework Equations Solid square cross section of beam: 100mm Material...

Hi rock.freak667, Sorry, can you just clarify how my calculations would fit into that equation? I can follow it through but I am unsure what your X stands for? Can you clarify. hf + x (hg - hf) ∴ 604.8 + x (2739-604.8) ∴ 604.8 + x (2134.2) Can you clarify for me? thanks a lot

Thank you rock.freak667

Homework Statement Find the enthalpy of steam at 0.4 MPa and 0.7 dryness Homework Equations The Attempt at a Solution At a pressure of 0.4MPa dry saturated steam has a total enthalpy of hg = 2,739 kj/kg. ∴ 0.7 kg of steam has an enthalpy of (0.7 x 2,739) = 1917.3 kj The...

Hi, I have been given the following questions to answer: write a report on the following: - the process by which plain carbon steel is produced - the process by which alloy steels are produced - the process by which aluminium is produced Now I am not entirely sure how to answer this and...

Hi there, thanks for your reply, I know I need to draw a force triangle of some sort, but unsure how to do it with the information I have. Even then, is this a correct polygon of force?? Thanks

Homework Statement Use the polygon of forces to demonstrate that a 200 kg crate on a 25o incline is in equilibrium on the slope. Homework Equations See attached The Attempt at a Solution Please see attached for my attempt, I think I am in the right ball park, just need to know what...

F = Friction N = Pressing Force At least that's how it is described in the learning material. Thanks v.much for your help both of you..

It is terrible, I am disgusted with ICS for the shoddy material. Some material is wrong, some answers to the progress check sections are wrong, and most of the questions in my assessment have not even been covered in a way of supporting my learning. Terrible! Anyway, thanks for your help...

The question states that at an angle of 30o the crates start to slip down the slope, so they set it at 25o for safety. It asks, calculate the coefficient of friction between the crates and the belt? The learning material I have been reading through is full of errors and mistakes, and...

Hi again, thank you for your replies. So is it as easy as 'tan30=0.577' which is the coefficient of friction in this example. Thanks
