# Maximum instantaneous Torque, how?

• TheRB4891
You can also include a higher factor of safety to ensure the shaft can handle the maximum torque under load.In summary, to calculate the maximum torque under load on an output shaft, you can find the force with the load and treat the shaft as a simply supported beam. Then, calculate the displacement using angular velocity and acceleration, and multiply it by the force to get the torque under load. Alternatively, you can also include a higher factor of safety for added assurance.

I have torque max and min on an output shaft without any load but need to calculate the maximum under load in order to choose correct shaft diameter, how do i go about this?

Alternatively, should i just include a higher factor of safety?

Thanks

Your torque under load should be computed by finding the force given with a load. At the end of a shaft it could possibly be treated as a simply supported beam using the area of a circle. Then your displacement will be calculated using an angular velocity and angular acceleration. Once those two are found, displacement and force, multiply them together

## 1. What is maximum instantaneous torque?

Maximum instantaneous torque is the highest amount of torque that can be produced by a motor or engine at any given moment. It is a measure of the rotational force that an engine or motor can generate.

## 2. How is maximum instantaneous torque calculated?

Maximum instantaneous torque is calculated by multiplying the force applied at a distance from the point of rotation, also known as the lever arm, by the sine of the angle between the force and the lever arm. This calculation is known as the torque formula: τ = F x r x sin(θ).

## 3. What factors affect maximum instantaneous torque?

Several factors can affect maximum instantaneous torque, including the size and strength of the motor or engine, the efficiency of its design, the type of fuel or power source used, and the load or resistance being applied to the motor.

## 4. How does maximum instantaneous torque differ from maximum continuous torque?

Maximum instantaneous torque is the highest amount of torque that can be produced at any given moment, while maximum continuous torque is the highest torque that can be sustained over a longer period of time. Maximum continuous torque takes into account factors such as heat buildup and wear on the motor or engine, while maximum instantaneous torque does not.

## 5. How is maximum instantaneous torque used in real-world applications?

Maximum instantaneous torque is an important factor to consider in the design and operation of machinery and vehicles. It is used to determine the power and performance capabilities of an engine or motor, and to ensure that the motor is strong enough to handle the load or resistance being applied to it.
