How do you calculate the torque needed to move 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 much torque is required to move a bike?
If you want to connect a motorized drive wheel, you will need to be able to generate that much force on the edge of the drive wheel. If you have a 5 cm radius wheel you would have a torque of 10 Nm (0.05 x 200), with a speed of 400 rpm (5 times greater than the speed of the pedals).
How do you calculate torque to weight ratio?
It’s very easy to calculate a power-to-weight ratio. Simply divide the power output of a vehicle by its weight. For example, if you have a car that weights 2000 pounds and has 250 hp, the PWR will be as follows: 250 / 2000 = 0.125 hp for every pound of car.
How do you calculate torque in physics?
The magnitude of a torque about a fixed axis is calculated by finding the lever arm to the point where the force is applied and using the relation |→τ|=r⊥F | τ → | = r ⊥ F , where r⊥ is the perpendicular distance from the axis to the line upon which the force vector lies.
How do you calculate maximum torque?
Torque on the loop can be found using τ=NIABsinθ τ = N I A B sin . Maximum torque occurs when θ = 90º and sin θ = 1.
What is torque weight ratio?
Definition: The ratio of torque to the weight of the moving part of an instrument is known as a torque/weight ratio. It indexes the performance of the instrument. The high value of the torque-weight ratio shows that even for the small value of deflecting torque, the pointer deflects and shows the measured value.
What is torque ratio?
A gear train can be analyzed using the principle of virtual work to show that its torque ratio, which is the ratio of its output torque to its input torque, is equal to the gear ratio, or speed ratio, of the gear train.
