How Many Miles per Hour is Bolt's 100m Equivalent to in a Car?
1 Answers
Bolt's top speed is equivalent to a car traveling at 40km/h. Here are the specific details: 1. Introduction: A car's odometer displays the vehicle's speed in km/h (kilometers per hour). The odometer consists of two gauges: a speedometer and a mileage counter. It is usually located directly in front of the driver's position. Identification methods include assessing wear and tear or checking the vehicle's maintenance records at a 4S dealership. 2. Principle: Traditional speedometers are mechanical. A typical mechanical odometer is connected via a flexible shaft containing a steel cable, with the other end attached to a gear in the transmission. The rotation of the gear drives the steel cable, which in turn rotates a magnet inside the odometer's housing. The housing is linked to a pointer, which is set to zero by a hairspring. The speed of the magnet's rotation affects the magnetic field strength, disrupting the balance and causing the pointer to move.
