I think i have to do the log of the graph then use quadratics and polynomials to compare and conclude. Does anyone know how i can use polynomial treadlined graphs to calculate the henry's constant which is in the x axis.
I was given the table below all i want to do is estimate the Henry's constant at -10 and 60 degrees. Just wondering the best way to go about this.
Would it be to take the log of the graph and add a treadline?

T1 and T2 is the time periods of two successive peaks taking from my graphs that show the oscillation to get the Td period of the damped oscillation.
The spring stiffness wasn't needed to calculate the damping constant
Thanks for the reply here's my sample calculation
Position 1 – 50.5 cm Damper Setting – Light
Offset on graph is 1.979mm
The offset of the graphs have to be added to the peaks
Xm = 0.751 + 1.979 = 2.73 mm Xm+1 = 0.379 + 1.979 = 2.358 mm
Xm / Xm+1 = 2.73/2.358 = 1.156...
Hi, I am currently doing an experiment to determine the the viscous damping coefficient (c) of a dashpot.
Where you move the position of the damper to determine the effect of the damping
but my results show that when the damper is closer to the pivot the damping increases but i thought the...

but it says in the handout that i got that the maximum allowabale shear stress is equal to
0.4 * the yield stress
ive included the handout in an attachment
thanks for the help by the way, but how do i find the shear stress then.
This is what i have done but the answer is still not the same
Od = 0.03340m
Id = 0.02664m
Shear modulus = 27GPa
yield stress = 172Mpa
Max allowable shear stress = 0.4 * yield stress
Max Angle 15 degrees
lentgh = 2.4m
T = (Stress/r)*J
(172MPa * 0.4 /0.0167)*...
hi i need to calculate the torsional stiffness of a sample, the data is in the excel file.
To work it out it = 1/samplek= 1/totalk - 1/machinek
the machine k was given as 42800NM/radian
the total k is the slope of the line which comes to y=658x
what i don't get is what am i meant to...
Hi, i have a shaft with OD = 33.40mm Wall Thickness = 3.38 mm length = 2.4m

My question is how did they get it as I am...
A 2.4 m long structural aluminium pipe (series 6063-T6) is used as part of a roof structure. As part of the design process it is required to assess the suitability of different sizes of pipe.

Hi its question 11-19, i triedto put it on word but it didnt let me upload. And I've got the solutions to the problem. and so when it says to calculate the weight it says
rowg * (R^2 - Pie * (R^2)/4 * 1
Hi i know how to do these problems but its calculating the weight of the fluid, which you have to do to minus it from the vertical force.
But in the solutions to the problem is say that the volume is R^2 - Pie *(R^2)/4 *1
The only thing i want to know is why is that...
so should i calculate the weight of the air using -
row(density of air) * 9.81 * volume of balloon
then do the buoyancy force minus the weight of air and the weight of the people(m*g)
but if this is correct I am not sure why my buoyancy force is lower than the weight as the weight of...
yeah, i thought i should take away the weight of the balloon and the people from the buoyancy force and that would leave me the force pushing it up and accelerating it. is this wrong.
does the buoyancy force=weight
Hi i have this question:
A balloon is filled with helium gas which weighs approximately one-seventh of what air weighs under identical conditions. The balloon has a diameter of 10 m and carries two people, each weighing 70 kg. Assume the density of air is 1.16 kg/m3 and neglect the weight of...
cheers for replying here what i done:
Q radiation - 0.95 * 5.67*10-8 * 1.4 * ((273+30)^4 -(273+10)^4) = 151.9
Q convection - 6 * 1.4 * (30-10) = 168
Qtotal = 319.9
god knows what I am doing wrong probably something really stupid, how did you do it
Hey I've got this question and the answer that is giving is 219.12 but i keep getting 319 could someone please help me out here's the question.
