What is the difference between real mechanical advantage and speed ratio?
the difference between the real mechanical advantage and the speed ratio is -the real mechanical advantage gets affected by friction so the real mechanical advantage gets smaller than the mechanical advantage you calculate. so the real mechanical advantage gets smaller than the speed ratio (because of the friction) and that's why the efficiency never gets 100% efficient (efficiency ; mechanical advantage/ speed ratio x 100(%))
Can Mechanical Advantage be greater than Velocity Ratio for any machine?
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
The ratio of the resistance force to the effort force is called?
The ratio of resistance force to effort force is a mechanical advantage.
What is the difference between a force multiplier and a speed multiplier?
A force multiplier increases the effort force and the mechanical advantage is larger than one (Which means it is easier to move a large load with a small effort). While the speed multiplier does not make the effort easier but makes the load move through a larger distance than the effort. The mechanical advantage of a speed multiplier is usually lower than 1.
A lever is used to lift a 50 kg object at a constant speed if the applied force exerted on the lever is 100N what is the mechanical advantage of the lever?
The weight of the 50 kg object is (50 x 9.8) = 490 newtons.In order to lift the object with a force of 100 N, you need a mechanical advantage of 4.9 .That's the net mechanical advantage of the lever system, including all of its friction losses.

How do you measure efficiency?
Efficiency= Mechanical Advantage Speed ratio X100 Mechanical advantage divided by speed radio X (times) 100
What is machines mechanical advantage?
it is d ratio of the load to the effort applied to move the load if mechanical advantage>1(ie L/E >1), the machine acts as a force multiplier otherwise as a machine to gain speed mechanical advantage is abbreviated as M.A.
What is the mechanical advantage of a machine which multiplies distance?
The mechanical advantage of the machine is"if you give small accelration , it will increase the speed of the engine... It is possible by mechanical

The advantages of mechanical shearing of sheep?
The biggest advantage is speed, it enables one shearer to get through many more sheep in a day. Speed is also an advantage for the sheep, the longer they are held for shearing the more stressful it is on them.
The ratio of the resistance force to the effort force is called?
The ratio of resistance force to effort force is a mechanical advantage.
What is the meaning of 'mach speed'?
Mach speed is by definition the ratio of the speed of fluid moving through an object vs sound. It is often used with mechanical objects such as diffusers and nozzles. Plane engines and car engines have items in them that have "mach speed."

How do you find speed ratio?
Distance input --------------- = Speed Ratio Distance output The distance input divided by the distance output equals the Speed Ratio.
Is CPU speed a ratio or interval?
