What is Torque? - Torque basics explained

The video tutorial explains the concept of torque using a wrench and nut example. It demonstrates how torque is calculated by multiplying force and distance, showing that a longer wrench provides more torque. The tutorial also covers gear ratios, explaining how low gears offer high torque and low speed, while high gears provide high speed and low torque. This concept is illustrated using examples of bicycles and cars, highlighting the need to shift gears based on speed and terrain.
