coefficient of area = A1 -A2/A1(t2-t1) =2m^2-2m^2/2m^2(80°C-20°) =0/120 =0 and coefficient of linear expansion using a as i can't find the proper symbol 2a = B b=2/a and then end up with zero as well. so I can't see how zero and zero will help me

Yes it does ask to use the steam tables. I am just more lost as to use which equations with the steam tables to help with my problem

Homework Statement I need help at identifying what forumala's to use to calculate the following (Density of Aluminium 2770kg/m^3 An aluminium plate has a mass of 5kg and a surface area of 2m^2. The temperature of the plate is 450°C. The plate is immersed in a container of water of which...

Homework Statement Determine by using steamtables for 2kg of steam - Boiling point if pressure is 5MPa - pressure if the boiling point is 195°C - enthalpy of evaporation at pressure 2800kPa - total elathapy in MJ required to produce 2kg of wet steam with dryness factor of 0.7 at a pressure...

To be honest I am not too sure.

I would go with B on your question.

Thank you for the feedback. I appreciate the advice! Is the graph I drew correct? can you maybe just explain to me what you mean with "A 45deg triangle has sides 1-1-√2 A 60-30 triangle has sides 1-2-√3 so. sin(45)=cos(45)=1/√2 so. sin(60)= √3/2, cos(60)=1/2"

Homework Statement I have done the following and would just like to know if it looks correct and any advice would be appreciated Four forces acting on a point 30N west 35N south 20N west 45deg north 25N east 60deg north 1. The sum of the vertical components and state the direction...

here is the diagram

my textbook doesn't really look at it. I've googled but haven't found much. here is an example 10 m light horizontal beam it has points ABCD A at 0m, B at 2m, c at 8m and D at 10m it goes positive 38N at A then to 34N at B then straight down to negative 16N the line then goes to C...
