They help us to transport things. Most vehicles have wheels. Cars, trucks, trains, motorcycles, buses, etc. Then there are things called conveyor belts. They too have an axle and a component similar to a wheel called a roller and has a wide belt running over it to transport goods in countless factories. Many machinery have components similar to a wheel/axle design that helps to make them function. Those are called pulleys. Various pulleys types exist for ropes, V-belts, cable, etc. One can not even imagine a life without the simple wheel and axle.
we wouldn't be able to drive cars or open doors.we would have to push cars.
Any number of applications: 1) bicycles; cars and trucks; wheelbarrows; skateboards to name a few. The axle allows the wheel to spin freely.
well, first im going to tell you teacher you are cheating. get a life and learn somthing
computer can help us in every work
There are 6 differant tyeps of simlpe mashine is a pully, wheel and axle,wedge,gear,inghalated plane,
Every philosophical thought about spirituality is recorded in scriptures as beliefs of life and after life.However, in scientific hypothesis with empirical evidence points to the existence of matter both as element matter and anti matter in the void. The wheel of life differs from the wheel of existence in all philosophical hypothesis or religious spirituality. The wheel of life is the relative temporal time of biological existence, while the wheel of existence is the perpetual existence (as element matter or anti matter) even after biological life ceases to exist.
they help discover our tempertures
yes of corse
It is very use full in every day life
Generally when purchasing tires for a vehicle how many you should purchase depends on the type of vehicle you drive. For all wheel drive or four wheel drive vehicles it is recommended to replace all four tires at a time to be sure all tread patterns match. For front or rear wheel drive vehicles the tires on both the front and rear axle should match each other and can be purchased in sets of two if needed. Tire rotation is generally done to maintain the tread life on your tires and tread life warranty from the manufacturer if any. Without rotating your tires they will suffer from excessive treadwear that can lead to early replacement. Tires should be rotated at intervals of every 6,000 to 7,000 miles or every second oil change to maximize tire life, rotating tires is designed to extend your tires life and won't help if your tires already need replacing.
It allows us to move objects with the minimal amount of friction. Would you rather drag an object or pull it on a cart? When you have wheels underneath the object your are transporting, there are only a few points touching the ground (the wheels). Therefore, there is less friction created when you pull the object. When there is less friction, there is higher efficiency. There are, of course, other ways it makes life easier, but that is one of the main ideas. Hope that helped. ;) i agree with the above answer but i would not say a wheel and axle is the main point of simple machines and their efficiency
