Q1. What means the General tolerances
Ans. 
General tolerances refer to the acceptable range of variation in dimensions or properties of a part or product.
• General tolerances are typically specified in engineering drawings to ensure parts fit and function properly.

• They are usually expressed as a range of acceptable values, such as +/- 0.1mm.

• Tolerances can vary depending on the specific requirements of the part or product.

• Examples of general tolerances include dim...read more

Q4. How to calculate motor power
Ans. 
Motor power can be calculated using the formula: Power (W) = Torque (Nm) x Speed (RPM) / 9.548
• Calculate the torque required for the application

• Determine the speed at which the motor will operate

• Use the formula Power (W) = Torque (Nm) x Speed (RPM) / 9.548 to calculate motor power
