The ratio of resistance force to effort force is a mechanical advantage.
That is called the "coefficient of friction". Note that it doesn't depend much on the area of contact, nor on thet speed.
That ratio is called the coefficient of friction. It is material-dependent, or to be more precise, it depends on the nature of the two materials that have contact.
That is called the "coefficient of friction".
The coefficient of friction.
The "coefficient of friction".
resistance force
1 (one).
The ratio of the force required to do work without the machine (load force, FL) over the force required to do work when using a machine (effort force, FE).
Sure, take your forearm, for instance. It is a lever that trades force for speed because the insertion points for the muscles on the bone (effort) are closer to the fulcrum (elbow) than the resistance (your hand). Your muscle contracts a short distance but that is translated to a greater distance at the hand. A short effort arm and a longer resistance arm gives a lever with a MA < 1
dynamic viscosity is the quantitative expression of fluid's resistance,while kinematic viscosity is the ratio of fluid viscous force to inertial force.
resistance force
The ratio of resistance force to effort force is a mechanical advantage.
1 (one).
Effort force:Load force. For example, if you put in 10 newtons of force and the load force was exerting 5 newtons the velocity ratio would be 2:1
Divide the length of the force arm by the length of the resistance arm.
The ratio of (distance) / (time), called "speed".The ratio of (speed) / (time), called "acceleration".The ratio of (force) / (area), called "pressure".The ratio of (force) / (acceleration), called "mass".The ratio of (mass) / (volume), called "density".The ratio of (distance) / (volume), sometimes called "fuel economy".The ratio of ( 1 ) / (time), called "frequency".The ratio of (energy) / (time), called "power".
It isn't. However, the ratio of magnetomotive force to magnetic flux will tell you what the reluctance happens to be for that particular ratio, in exactly the same way that resistance isn't dependent on current, but the ratio of voltage to current will tell us what the resistance happens to be for that particular ratio.
The ratio of the force required to do work without the machine (load force, FL) over the force required to do work when using a machine (effort force, FE).
voltage to current ratio is called resistance. it is d opposition offered to d flow of charges.........
It is the inverse of the displacement of the point of application in the direction of of the force.

The ratio of output force to input force for a machine is called its mechanical advantage.
