Hello guys,
I am doing some basic design work and can't remember how offset torques work.
I am doing the sum of the torques should be equal to 0 in order to find the tipping point around either of the wheels.
My problem is with the 1000N applied at to top taking the pivot point around the...
Homework Statement
A buffer at the end of a rail track consists of a hydro-pneumatic shock absorber. The gas chamber of the absorber has an cylindrical geometry consisting of a length of 800mm and 0.5 m diameter and a pressure of 5 bar. Calculate the final pressure and stroke if a 2 tonne...
I got the first part, but for the second part of the question,
I used the formula:
m*c*deltaT/t = hA(Ts-Tf)
Where Ts is the average temperature of the copper during cooling and we are solving for T, however i do not get the right answer. The answer is 5.4hours.
Which part of the equation...
Hey, I was doing some revison for a test and i came across this question which I can't get my head around
a clyndrical copper block, 0.3m in diameter and 0.4m long is initially at a uniform temp of 60°C and half its curved surface is exposed to a heat flux of 450w/m^2. If the complete surface...
Hey,
I came across this question in my textbook, and there isn't an answer for it in the back, so I would just like to check if I have my head around it.
The question is:
2 projectiles are launched at the same angle. Projectile 1 reaches a max height of twice that of the projectile 2. What...
ok, sorry, there are 3 masses, m1, m2 ,m3, all different.
m1 and m2 are on a table top, and m3 is hanging freely of the side of the table. they are all connected and are accelerating.
my question is: is the tension at m1 due to m2 and m3 the same as the tension at m2 due to m1?
Hey, I have a question on if the tension on either end of a string is equal. For example, if there are 3 blocks of different mass, one hanging of the side of the table and two on the top of the table, will the tension on the string from m1 to m2 be the same as the tension from m2 to m1?
