Thank you both this is exactly what I needed.

Hi There, Why is a pipe with a smaller diameter able to withstand a greater internal pressure than a pipe made from the exact same material and wall thickness but larger diameter? Thank you

Thank you very much for your quick response

Hi There, I have constantly come across the fact that as fluid (hydraulic oil say) travels along a pipe you will see a continual drop in pressure the further you travel down the pipe. Am I right in saying that the pressure at any point is simply the result of the resistances (friction with pipe...

I have a quick question in relation to the Engineers theory of bending when applied to simply supported beams. I am using the following portion of the theory to determine the stress in a simply supported beam when subjected to bending: Stress = My/I Is it appropriate that I compare the...

Homework Statement I need to rearrange the change in kinetic energy equation for mass Homework Equations Change in Kinetic energy = 0.5mv^2-0.5mu^2 The Attempt at a Solution [FONT=Times New Roman]I factorised the right hand side to give: [FONT=Times New Roman]Change in kinetic energy...

Perfect so, Change in Kinetic Energy = 0.5mv2^2 - 0.5mv1^2 Thank you for your help DrClaude

Ok, If I were to say that Change in Kinetic Energy = mv2^2 - mv1^2 Where v2 = final velocity and V1 = initial velocity Would I be on the right lines?

KE=0.5mv^2 is the correct equation for kinetic energy, but we are given that. Am I right in saying that I need an equation that relates the change in Kinetic energy to mass?

Homework Statement A) A car moving at 18 m/s is accelerated to 35 m/s. If the change in kinetic energy is 154 kJ, determine the mass of the car. Homework Equations [FONT=Times New Roman]KE = 0.5mv^2 Kinetic energy = change in momentum = mv2-mv1 The Attempt at a Solution [FONT=Times...

Thank you very much for your response SteamKing, it was very usefull. Just one other thing in relation to this topic, I have attached a basic representation of a shear force diagram. You will see that the shear force line passes vertically through the zero line, how would the shear force...

Hi there, I have created lots of shear force and bending moment diagrams for simply supported beams. I have used the maximum value on the bending mement diagram for bending and stress equations, but I have never found any real use for the shear force diagram. Yes they tell you the distribution...

Thank you Ken G

I have a problem in relation to the pressure in a closed piston and cylinder assembly, I know the compression ratio and want to work out the pressure when the volume is at its lowest, boyles law only seems to works if the temperature remains constant but I know that as the piston moves and the...
