On another note: In the attached png. I am confused on they calculated "3/2" for the height I am thinking if its the centroid?

Homework Statement What is the difference between these two formulas Homework Equations 1.Force=rho*g*h*area 2. Force=rho*g*volume 3. Force=rho*height*Area Where rho= specific weight of fluid The Attempt at a Solution I am guessing that 2 is for sphere or cylinders and for 3 i think it is...

Homework Statement The rectangular gate shown in section is 3 m long (perpendicular to the paper) and is hinged about its upper edge B. The gate divides a channel leading to a fresh-water lake on the left and a salt-water tidal basin on the right. Calculate the moment, M, on the shaft of the...

The resistance value of a thermistor at a specified temperature with negligible electrical power to avoid self heating. Usually base resistance will be defined at 25 °C. Its a NTC looking shape I think Y is resistance X is temp. Not sure At 100C: R= 0.08 Could I plug in 25 C and solve for Y?? .

Using the regression eqn. Find the base resistance of the thermistor. Find the temp. Of the boiling water using this eqn. Y=1.54e^-0.059x How do I go about solving this problem

Homework Statement Fracture load = 56000lb Radius=3 in Compressive strength = (F/pi*(r)^2) CS=630psi I was wondering if I did it right. Thanks

The longest cured cement was the strongest with compression strength

This is the whole lab questions about the concrete lab. Questions to be addressed in the lab report: 1. Fill in the group data sheet posted in the lab and include this table in your report. 2. Your report should include all data related to the preparation of your concrete, the group data...

Homework Statement How does the compressive strength of concrete samples compared to the expected compressive strength of cured concrete. If different explain why. The Attempt at a Solution I think the question is asking what is the relationship between time and curing. And I think that the...

Ok, I understand now. Thank-you all

Homework Statement A= 400mm^2 d=7.5mm v=1.5 kappa= 4.0 offset=8.00mm [/B] Click on the dielectric tab. Configure the single capacitor circuit by using the parameters given in the circuit diagram to the right. This capacitor with its offset dielectric slab is equivalent to two component...

Okay thanks for the first post

I'm not understanding how they were able to obtain the mass and y bar since they only gave out this For 1=24kg/m^2 2=36kg/m^2

Yea that's what I thought as well for the rectangles. 175x300 And the answer is wrong as well it should be 95.6 for y bar Thank-you

Hello can anyone explain how they got 157x210 for the rectangle
