i think it means to push or pull
what is the machine for? Many ways to make something for kids but what is the purpose
pulleys, levers, pendulums
use when only needed
To calculate the mechanical advantage of a compound machine, you need to know the input force applied to the machine and the output force obtained from the machine. Additionally, you will need to understand how the individual simple machines within the compound machine are connected or arranged to determine the total mechanical advantage.
A machine can change a force by using mechanisms like levers, pulleys, gears, or hydraulics to amplify or redirect the force being applied. These mechanisms can help increase the force applied by the machine, change the direction of the force, or transfer the force over a distance.
1. Take a small input and you get a large force.
A machine saves you force, changes distance, and changes direction. Those are the three ways in science that why machines are useful.
The inclined plane is a simple machine. Simple machines were invented because they allow people to do more work in easier ways.
The bed ways of a lathe in itself are not hollow, but the area between the ways are. This is primarily to reduce the weight of the machine and also the cost due to much less material used to manufacture it.
output force is al ways less than input force
One way to measure softness is to use a machine that records how much force is required to deform a sample of the material by a certain amount. The less force, the softer the material is. Another way to measure softness is to have people feel a sample of the material and compare it to samples of other materials that already have softness ratings assigned to them. The mechanical testing works very well for materials that are very uniform and are deformed in simple ways. The human sensory method works best for less uniform materials that are handled in more complicated ways (like bathroom tissue, for instance).
Do you mean one that obeys SHM (simple harmonic motion)?It will just basically, as it goes through its oscillation, transfer energy between potential energy and kinetic energy. There are other machines that use SHM, particularly in the field of electromagnetism, but they work on different princiapls, although still obey SHM.
