to gain strength, which is important in football
Most machines especially mechanical machines that don't use electricity rely heavily on physics. Gravity, air resistance, water resistance and other forces along with moments and mass. Hope it helped. MistroJoe

Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
Carbon is used for brushes becauseit has a negative temperature coefficient of resistance -i.e. its resistance falls as its temperature increasesit is self-lubricatingit easily takes on the shape of the commutator/slip rings, improving area of contact
Bands used in exercise provide resistance similar to that of weight machines. However, the resistance is constant, meaning that you'll get more of a workout through the same amount of time, as well as strengthening stability muscles which will increase coordination. Resistance bands are also more portable, easier to store, and much less expensive than traditional weight machines or gym memberships.
The features do the best elliptical machines have adjustable resistance and movable handles. The things they have vary from brand and model.
Magnetic rowing machines are commonly used in the home as they are the cheapest and quietest.They control resistance by means of electromagnets that engage a mechanical brake with a flywheel.
Simple machines can be used to transport things.
The machines used at Pinkberry are frozen yogurt dispensers.
are machines used to simplify work in the office.
The machine is a football because you can throw it and kick it and a machine is a thing that needs force to help complete a task.
Tension is the force being used in Simple Machines. As well as simple machines may have a little gravity used, tension is the most used.
