Does Weight Affect torque?
Dividing horsepower or torque by vehicle weight will give you power to weight ratios, which has a big impact on acceleration and performance. The same engine can be paired with different transmissions to produce faster acceleration or pulling power by varying the gear ratios.
How do I calculate how much engine I can pull?
The formula that relates mass, force and acceleration is: F = m*a , where F is the force, m is the mass and a is the acceleration. So a = F/m would be 14.715 kg*m/s² divided by 2 kg and therefore: ~7.358 m/s².
What gives a car more torque?
The amount of torque produced is directly proportional to the air flowing through the engine. Large engines pump more air and, therefore, produce more torque.
How much torque do I need to turn a worm?
Choose gearing so that the torque required to turn the worm is 10-30% of the torque required to lift the weight, for a reasonably efficient solution. Then you can select a motor for this torque.
How much torque do you need for a motor?
That, in addition to the 4.4 N just to balance gravity means you need 5.8 N upwards force. At 0.05 m radius, that comes out to a torque of 0.28 Nm. There will be some friction and you want some margin, so in this example a 0.5 Nm motor would do it. Note also that torque isn’t the only criterion for a motor. Power is another important one.
How much torque does a 450 g mass need?
The gravitational force on your 450 g mass is 4.4 N as you say, so the torque just to keep up with gravity is (4.4 N) (0.05 m) = 0.22 Nm. However, that is the absolute minimum torque just to keep the system in steady state. It leaves nothing for actually accellerating the mass and for overcoming the inevitable friction.
How much torque do you need to accellerate a mass?
To get the real torque required, you have to specify how fast you want to be able to accellerate this mass upwards. For example, let’s say you need at least 3 m/s². Solving Newton’s law of F = ma: That, in addition to the 4.4 N just to balance gravity means you need 5.8 N upwards force. At 0.05 m radius, that comes out to a torque of 0.28 Nm.
