What is the general torque of a human hand?
2 Answers
Human hand torque generally ranges from: 60N—120N. The following is an introduction to electric vehicles: 1. Introduction: Electric vehicles (EVs) refer to automobiles that use electric energy as a power source and are driven by electric motors, belonging to the category of new energy vehicles. 2. Content: This includes Battery Electric Vehicles (BEVs), Hybrid Electric Vehicles (HEVs), and Fuel Cell Electric Vehicles (FCEVs). Due to their relatively smaller environmental impact compared to traditional vehicles, they are widely regarded as having promising development prospects, although the technology is not yet mature. 3. Speed Control: The motor speed control device is set up for functions such as speed change and direction reversal in electric vehicles. Its role is to control the voltage or current of the motor, thereby managing the driving torque and rotation direction of the motor.
Having driven for over a decade, I've developed a deep understanding of torque. The average person's one-handed grip torque is around 25 to 35 Newton-meters—just enough to twist a bottle cap or tighten a simple bolt. But when it comes to cars, that's nowhere near sufficient. For instance, when changing tires, wheel nuts need to be tightened to over 100 Nm. I remember trying to do it one-handed once—exhausted myself and still couldn't get it tight enough, nearly causing an accident on the highway. That's when I invested in a torque wrench. Now, I can measure exactly how much force is needed. Here's my advice: don't skimp on tools. Safety comes first. Keeping a torque wrench in your garage not only makes the job easier but also extends the lifespan of your car parts. It's a smart investment.
