Great

what was punched into the calculator to come up with 14.3?

At the end, how did you get the -1 after the equation for A

if we were using conservation of momentum, why are you using mv+ft=mv? shouldn't it be m1vi+m2vi=m1vf+m2vf ?

Didn't understand anything from this video

Teach us thermo 2

thank u sir, but can you try solving, using rc? I tried it but i got a different answer

Thank you so much for helping to finish my final ❤

I understand that the brace restrains the displacements at the midpoint. But I think that the boundary conditions at midpoint should be clamped instead of pinned for the weak axis because there is a continuity in the column and the midpoint is not free to rotate

I understand that the brace restrains the displacement of that point. But I think that the boundary conditions at that point are clamped because there is a continuity in the column and it is not free to rotate at that point

please start thermo 2, youve saved me in thermo

paypal is not available in my country. is there any other way i can access the solutions?

Bro, the derivative of x² is 2x. No chain rule

I ❤ you from South Korea

Typical structural engineering problem

Use Pythagoras theorem to find R or use the angles

Too fast professor

you have to realize that. this is math math is very important for everyone By education purpose. Beside of other subject so every calculation was very important so you have to find out whats your wrong! your application handwriting was not good be carefully and good life. I hope you will be understand.

at 10:18 why did we look for at 150 MPa ? shouldnt we look for 150 kPa?? and you said that it is table A5 saturated so there is kPa

Professor can I ask question from there?

ola why do use q+w = deltah is in't q+w = mdot delta h for turbine

Foe anyone wondering why the specific volume stays the same , it is not because of the rigid tank but because of the rigid tank + mass stays same. rigid tank alone tells us only the volume stays the same not the specific volume

cant get past 15 seconds mark with all the coughing

12:33 bless you

Great video! What software are you using to write?

For theta p shouldn’t it be 2theta p? Why not put 2 there like u did before?

Thanks so much mate

In combined loading problem, are we considering a 2D square element on the surface of the member or a 3D cube stress element? I am getting confused on what the orientation of the element chosen is and how the stresses act on that element.

Really helpful thanks so much ❤

I need help sir. I didn't clearly understand how we got the expression for Rmax.

Why didn’t u add 90 for sigma y sir?

Edit: great job

Get the ball rolling

thank you so much for these🙂you saved my final

R you drunk?

May I ask why N is in y-axis and V is in x?

why -Mz and not My? im still 😕 😕 confused, because it's -(3000)(3,5)

Engineering Mechanics C+

does the question ask about the mass flow rate of the stem? why we calculate the mass flow rate of liquid? isn't they are diffrent

Great explaination

all I heard is "cough, cough, cough, cough,cough, cough,cough, cough,cough, cough,cough, cough,cough, cough,cough, cough,cough, cough,cough, cough,cough, cough,cough, cough,cough, cough,cough, cough. thx anyway.

can we just use rho*v dot to find the mass flow rate. v dot is 4l/40 min

is it steady flow process

quick question over here. why do u use the 10 gals for part A . because it asks for the volumetric flow rate at the hose(inlet) whereas 10 gal is for outlet

I DONOT UNDERSTAND WHY U DO NOT USE Q out or W in ur equation

by Carnot you say it is the best we can do but how would that be theoretical? wouldn't the best output theory wise would be a reversible engine? please tell me what you actually mean when you state that an engine is a Carnot engine

163.782 KJ?

would you say that a hypothetical perpetual machine would have 100% efficiency since there is no energy applied to begin with and we still get some work, be it exponentially tiny? would you say that a semi perpetual machine ( work is required just to start the perpetual motion) would also have a 100% efficiency?

Absolute pressure is gauge pressure + atmospheric pressure right??
