Is the mechanical advantage a constant value or can it be made to vary?

The mechanical advantage is a numerical relationship among the sizes of
physical components of the machine. It's constant as long as the sizes
of those parts of the machine are constant.

How is a lever different from a machine made with ropes and pulleys?
Both pulleys and levers are mechanical devices designed to gain an advantage over an inert load force and both are simple machines. The main difference with a pulley system is the direction of force, and the effect can be different.
How can you make your vernier callipers more sensitive or more accurate?
the instrument can be made more sensitive by making vernier constant less ie by incresing the no of division on vernier scale or by decreasing the value of main scale.
Why handles of metal cutters are made long?
To take advantage of leverage.

Is a robot living or nonliving?
Non-Living, it is an artificial mechanical device made to mimic a human being.
What are the advantages of a mined diamond?
Mined or natural diamonds are more expensive than man-made diamonds. If monetary value is an advantage, then a mined diamond has the advantage of value.
What factors determine the mechanical advantage of pulley system?
Disregarding friction and other losses, mechanical advantage N = F/f which is force into the system f and force out F. We can think of each wheel in a pulley system as being part of a lever. And each lever has its own mechanical advantage n = F/f = L/l where L is the long end from the fulcrum and l is the short end from it. And there we are. Those lengths, L and l, have their analogs in the pulley wheel radii or diameters (they are equivalent). So if you have a pulley system made up of two connected wheels, with diameters D and d, the mechanical advantage of the system is N = D/d or R/r for radii. If there are more than two wheels, we can simply multiply the mechanical advantages between each pair of connected wheels to get the total mechanical advantage of the entire system.
How can a particle have a spin of 0.5?
Due to quantum-mechanical laws, the spins of particles have to be some integer multiple of a base value. This base value is 1/2, in the selected units, which relate to the reduced Plank's constant. Using different units, it might be multiples of something else. For example, using Plank's constant (instead of the reduced constant), it would be multiples of 1/(4 x pi). Special units can also be made up for particle spin, to make the spin a multiple of 1, or in fact of any other number you choose.

Why is a Russian made watch expensive to buy locally?
Russian made watches are expensive locally because they are in demand because of the craftsmanship and the look of Russian made watches. Most Russian watches are good quality, well made, mechanical, and a good value.
How did the mechanical reaper help?

How does a well work for a pulley?
Most wells do not use pulleys. The traditional style simply winds the rope around the shaft. The mechanical advantage is made by the length of the crank handle, in relation to the diameter of the accumulated rope on the shaft.
Are sand dunes made by chemical weathering or mechanical weathering?
I believe sand dunes are mechanical.
Is a toonie a mechanical mixture or a suspension?
Its a Mechanical Mixture.Why? Because its just out of a metal. Also its made out of a outer ring of the toonie is 99% nickle. The center is 92% copper, 6% aluminium, and 2% nickle... Thats why its a Mechanical Mixture.
