Homework Statement Steam flow through a pipe at a pressure if 8bar and a temperature of 340C. A valve is opened and steam is allow to enter an insulated enclosure whose volume is 0.5(m^3), until the pressure equals the quantity of steam that enters the enclosure. Homework Equations Q...

Hey guys, I'm really really confused on how we come about the plane z = x - y. I always have been and it's proving to hurt my progress, any help will be accepted.

Thank you for your response, I'm sorry, I still don't understand how you are getting du/dx = ε, I understand up to the point where you say, "is related to the strain". The rest I understand, thanks! Is it just that du is the extension and dx is the original length of a segment of length...

Homework Statement ε = xe-x2 L = L Homework Equations ε = ΔL/LThe Attempt at a Solution xe-x2 = (ΔL - L)/L ∴ ΔL = Lxe-x2 + LI really don't understand how the solution got "dx" on the first step, also the delta L. I want to understand the first step, the rest of the solution I understand...

Thanks for the reply, I understand that the beam is pulling the block up, I just don't understand where it fits into the calculation, as I have calculated the corrosponding angular velocity of the bar. Is there a formula I am missing?

Homework Statement As the picture says, we are trying to find the reaction force on the bearing at A: We are given: M(block) = 26.1kg M(bar) = 8.7kg L(bar) = 1.8m V(block) = 6.2m/s Homework Equations What I have attempted the solution with are: ƩF = ma ƩM = Iα I0 = (m*L^2)/12...

Homework Statement As the picture shows, we are given several variables, but I am near completely lost. I am behind in my course and am trying to catch up as best as I can but this problem is really hard for me Homework Equations The equations that I have used are; parallel axis...

Homework Statement As shown by the attachment we are given the distances and the 28kN force Homework Equations relevant equations are equations of equilibrium; ƩFy & ƩFx = 0; ƩM = 0; The Attempt at a Solution First found By by summing the moments around point A; (clockwise...

As given by the attached question, we are given: The force on the pulley, 51N The angle of the pulley, 31 degrees The mass of the box, 15 kg The angle of the incline, 31 degrees The kinetic friction coefficient, 0.5 I think the relevant equations are: ƩFy = 0; ƩFx = ma...
