Well, I think the force tension is 150 N.
F = Fbrk - Fmass
F = 150 N - 100 N
F = 50 N
Then F total is,
Ftot = F + Fmass
Ftot = 50 + 100
Ftot = 150 N.
But I wonder if the speed much slower, 0.1 m/s and if the speed higher 10 m/s,
by the equation above the tension of rope at braking is...
(The weight scale = 10 kg).
After initial force, now the mass is lowering down at constant speed of 1 m/s.
The motor with pulley's radius of 1 meter is exerted 100 Newton m to keep constant V.
The motor speed is about 9.55 rpm.
* All other weights, inertia and frictions of the system is...
Now I am working with a DIY Luffing Jib Crane.
Mys subcon said that:
Tension of red rope for hanging a blue box load at the tip of the boom i(A) s as the same as hanging it with pulley and tied to the motor/ground_B (System in a Static Load Condition)..
Blue Rope and Pulley weights are...
My calculation for B.
I assume an extreme condition that the center of gravity is right bellow 1 ton anvil (for easier cal).
So I draw straight line as a lever from fulcrum to the that center.
The total moment Inertia is:
Inertia of 1 Ton anvil plus (100N x cos a) x length of red...
Blue box is welded to black base, or blue and black is a one single unit device.
Now if there is a 100N horizontal force acting to blue box in top left side like pic attach:
Is Tension of Red Rope (T) the same for A and B condition?
Ok case closed.
I just wonder from this picture:
Is Tension in rope T, the same for hanging an anvil at Bottom Right (A),
or if we put it on Top Right? (B).
The hinge or fulcrum slightly off center to the left side.
Because now we have weight of big blue box.
is the center of gravity taking...
Dear All Masters
I have problem with slewing bearing crane.
My subcon made a crane that have a very high platform deck form slewing bearing.
They said it is fine and the height is not an issue as it is in lower place.
I know the higher the load from slewing bearing,
the bigger the force or...
Actually it is a simple one, but the point of view of the force acting in pic attach of some people are different.
The adding weight of hoisting slink blue and the pulley is neglected.
I think the...
I want to loading about 14 ton of CMS (Carbon Molecular Sieve) into a PSA Nitrogen Producer tank.
The tank is 5 meter tall with 2 m in diameter.
What is the best, simplest and fastest method to load the pellet of CMS into that big tank?
I consider this mortar screw pump and connect...
