Lnewqban's latest activity
-
I do want to know the tensile force exerted on the rope when the outer cylinder descends; F can be considered as the tensile force of... -
Lnewqban replied to the thread I 1:1 versus 2:1 Mechanical Advantage debate.Welcome, @cmars ! Perhaps it is not completely correct to call it mechanical advantage. The fixed pulley, which is the only device in...

I agree that is confusing, but since the question asks for a tension there was, presumably, some mention of a rope in the original text...

Lnewqban reacted to jedishrfu's post in the thread I 1:1 versus 2:1 Mechanical Advantage debate with
Like.
Your self-haul with a single fixed pulley has a 2:1 MA in the ideal case: half the force, twice the rope. The confusion clears the... -
Lnewqban replied to the thread Physics Problem on Tension in Water.Isn't the force vector represented in the OP diagram pointing in the wrong direction? The outer cylinder would naturally tend to fall...

Lnewqban reacted to berkeman's post in the thread Lawn/Garden Determining Ramp Length for Ground Clearance with Like.
In case you decide to make it/them on your own, I'll share my old design. I built a very strong motorcycle ramp (strong enough for...

Lnewqban reacted to kuruman's post in the thread Tension in a string connecting two blocks having equal and opposite velocities with Like.
The real problem with wording is in the statement of the question. The masses cannot be unequal and have equal speeds in opposite...

Lnewqban reacted to kuruman's post in the thread Tension in a string connecting two blocks having equal and opposite velocities with Like.
It is not necessary to assume that the CoM has some velocity. The two masses orbit each other while the CoM is stationary. This is shown...

Lnewqban reacted to kuruman's post in the thread Tension in a string connecting two blocks having equal and opposite velocities with Like.
And what external entity is there to provide the centripetal acceleration to the center of mass? Please look at the figure in post #8.

Lnewqban replied to the thread A Condensate rate of water for an air conditioning cooling coil.You are welcome. Condensation formation and dripping flow on tubes and fins, which depends mainly on humidity content of air, tend to...

Lnewqban reacted to kuruman's post in the thread Projectile problem: A block released from a balloon with Like.
That's the least of one's worries. We are given the velocity of the balloon as 12 m/s. What is the direction of that velocity...

Lnewqban replied to the thread A Condensate rate of water for an air conditioning cooling coil.Welcome! Number of rows in the coils is also important. Calculation is very difficult, due to formed film of water around the tubes...

Lnewqban reacted to kuruman's post in the thread Tension in a string connecting two blocks having equal and opposite velocities with Like.
Let's examine whether the masses undergo uniform circular motion as assumed by the OP by looking at the tension as the centripetal force...

Lnewqban replied to the thread Tension in a string connecting two blocks having equal and opposite velocities.Just imagine a huge mass and a very small mass attached at each end of the string. Then, a horizontal rotation being induced, assuming...

Lnewqban reacted to .Scott's post in the thread Tension in a string connecting two blocks having equal and opposite velocities with Like.
If I was editing that workbook, I would mark up that question. Those velocities are presumably relative to the table. And "for any...
