Most people use levers to turn on and off a giant machine. But I only know that scientists use it. =)
why are levers useful
Levers will wear and tear after use and money will have to be spent to repair or replace them.
The main types of bike brake levers available in the market are mechanical brake levers and hydraulic brake levers. Mechanical brake levers use cables to actuate the brakes, while hydraulic brake levers use fluid to transmit force to the brakes. Riders can choose between these two types based on their preferences and riding style.
Levers are used in various applications today, including construction equipment, manufacturing machinery, and fitness equipment. They are also found in everyday items such as door handles, scissors, and bike pedals.
Mechanical advantage is not the only reason to use levers.
Scales and kitchen use.

Levers and linkages are mechanical systems that transfer forces or motion from one point to another. Levers use pivots to amplify or redirect forces, while linkages use interconnected bars to control motion. By adjusting the position and orientation of their components, levers and linkages can produce a wide range of mechanical advantages and movement patterns.
because it makes things easier to lift..... that's why you use it i think.........
People use levers in a variety of situations, such as on seesaws at playgrounds, in construction to lift heavy objects, and in tools like crowbars to pry things apart. Levers are also used in machinery and equipment to make tasks easier by providing mechanical advantage.
A lever is a simple machine that makes work easier for use; it involves moving a load around a pivot using a force. Many of our basic tools use levers, including scissors (2 class 1 levers), pliers (2 class 1 levers), hammer claws (a single class 2 lever), nut crackers (2 class 2 levers), and tongs (2 class 3 levers).
