How much torque is required to rotate an object?
To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r). If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.
How do you calculate the torque of a hollow cylinder?
I’m selecting a gearmotor drive package to turn a hollow cylinder that is used to dewater sewage sludge….Open Calculator.
| T = | Required Torque, lb-ft |
|---|---|
| t = | Time to accelerate the load, seconds |
| W = | Weight of object, lb |
| R1 = | Outside Radius of cylinder, ft |
| R2 = | Inside Radius of cylinder, ft |
How do you calculate the force required to rotate an object?
Follow these simple steps:
- Find the mass of the object – for example, 10 kg .
- Determine the radius of rotation. Let’s assume it’s 2 m .
- Determine the velocity of the object. It can be equal to 5 m/s .
- Use the centrifugal force equation: F = m v² / r .
- Or you can just input the data into our calculator instead 🙂
What is the torque equation for the hollow shaft?
Torsion Resisting Moments from Shafts of Various Cross Sections
| Shaft Cross Section Area | Maximum Torsional Resisting Moment – Tmax – (Nm, lbf ft) |
|---|---|
| Hollow Cylinder Shaft | (π / 16) τmax ((2 R)4 – (2 r)4) / (2 R) = (π / 16) τmax (D4 – d4) / D |
| Ellipse Shaft | (π / 16) τmax b2 h |
| Rectangle Shaft | (2 / 9) τmax b2 h |
How do you calculate torque from force?
The equation, Force = Torque ÷ [Length × sin (Angle)], converts torque into force. In the equation, Angle is the angle at which the force acts on the lever arm, where 90 degrees signifies direct application.
How much torque is required for a gas cylinder to rotate?
Join ResearchGate to ask questions, get input, and advance your work. Ideally, of course, no torque is required, once the cylinder has reached 50 rotations per second. Torque is only needed to get it to that speed, and then, at speed, only to counter the effects or wind drag and friction in the shaft bearings.
What is torque and why is it needed?
Torque is only needed to get it to that speed, and then, at speed, only to counter the effects or wind drag and friction in the shaft bearings. Assuming you are rotating the cylinder around its axis, then the cylinder can be modeled as a ring, or a disk, depending.
How to calculate the required torque to start the barrel rotating?
The required torque to start the barrel rotating is based on the combination of the polar moment of inertial of the barrel with its load and the desired time to accelerate the rotation to the desired speed. After reviewing more, torque resistance and drag are negligible. I would want to use inertia, I = (m*r^2)/4 + (m*L^2)/12?
How much torque is required for 50 Hz rotation?
The more rapidly you want to achieve 50 Hz rotation rate, the more torque is required, but for a shorter period of time. It’s analogous to F = ma. Ideally, of course, no torque is required, once the cylinder has reached 50 rotations per second.
