Using a lever and using Wheel and axle is completely different.
Some Practical situations could be :
The thing is that where wheel and axle is used at that place lever cannot be used and vice versa.
You cannot use a wheel and axle to open cars door hence lever is used.
You cannot use lever to move a car there fore you need wheel and axle.

A fulcrum in a lever is very important because without a fulcrum a lever isn't a lever , and the fulcrum is the main part of a lever.
A common lever is used to move an object
first order lever
It is a third class lever machine because The effort is in between the load(food) and the fulcrum(handle)
That depends where the fulcrum is. The closer the fulcrum is to the load (one-class lever), the easier.
cuz .... they are round
The least count of a lever balance is the smallest weight difference that the balance can measure accurately. This depends on the precision of the balance and is typically mentioned in the balance specifications provided by the manufacturer.
John Charles Weaver Lever has written: 'A practical treatise on organic diseases of the uterus' -- subject(s): Uterine Diseases
A stapler is a lever because it uses a pivot point and a force to join papers together. It can also be considered a wedge because the staple itself has a wedge shape that penetrates the papers, holding them together.
A fourth-class lever is a type of lever where the input force is between the fulcrum and the output force. In this arrangement, the load arm is longer than the effort arm, resulting in an increase in speed but a decrease in force. Fourth-class levers are not very common in everyday situations but can be found in certain biological systems, such as in the human body.
Look on the underside by the lever, it will be a number at least 6 digits long.
really?A2. Or at least a lever and an axle, which acts through a further rotary device for its action.
none of them are the least helpful they all help things move upward except the lever but the most helpful one is the pulley a pulley takes up less space and it goes straight up so u can use less force
Cadillac were the first to manufacture a car with are what are the general 'standard' controls of today, the clutch, brake and accelerator as pedals, steering wheel and a gear lever and handbrake next to eachother. Before this cars were hideously complicated to operate The first practical car was built in Germany by Karl Benz in 1886.
Yes, it uses many different "simple machines", including wheels and at least one lever on a fulcrum.
A foot lever is a device that is operated by the foot to control or activate a mechanism or machine. It is commonly used in vehicles, musical instruments, and machinery to provide a means of controlling various functions without using the hands.
A lever is a simple machine consisting of a rigid bar that pivots around a fixed point, called a fulcrum. It is used to lift or move objects by applying force at one end. Levers are classified into three types based on the relative positions of the fulcrum, effort (input force), and load (output force).
