What if a pulley has a mechanical advantage of 1?

A pulley can either change the direction or the force, but not both. Since a single fixed pulley makes an object go up when pulled down, it has changed direction. So it can't also change force.


When did Gutenberg make the machine?

Gutenberg invented Movable Type printing- using a printing press- the usual manually operated , somewhat guillotine-like up and down type was actually out earlier but Gutenberg pioneered movable type- wood type, wood and metal composite- it went through a variety of trials and errors. The Gutenberg Bible was published in l45l, this is the first major book printed by movable type. Earlier Bibles were laboriously hand-scribed with such things as illuminated manuscripts- it is possible stencils were used to get uniform curlicues- but The Gutenberg Bible was the first printed with movable type.


What is centrifuge swing-out rotor?

A Centrifuge Swing-out Rotor is a part of a centrifuge which attaches to the motor and holds the sample tubes. A swing-out, as opposed to a Fixed Angle rotor, has holders that move from vertical to horizontal as the centrifuge speeds up.


What is a limited rotation hydraulic motor?

A limited rotation hydraulic motor provides a rotary output motion over a finite angle. This device produces a high instantaneous torque in either direction and requires only a small amount of space and simple mountings. Rotary motors consist of a chamber or chambers containing the working fluid and a movable surface against which the fluid acts. The movable surface is connected to an output shaft to produce the output motion. Figure 4.1 shows a direct acting vane-type actuator. In this type, fluid under pressure is directed to one side of the moving vane, causing it to rotate. This type of motor provides about 280° rotation. Rotary actuators are available with working pressures up to 350 kg/cm3 (4978 psi). They are typically foot mounted, flanged or end mounted. Most designs provide cushioning devices. In a double vane design similar to the one depicted in the figure above, the maximum angle of rotation is reduced to about 100°. However in this case, the torque-carrying capacity is twice that obtained by a single vane design.


What are the functionS of a drill press?

-The drill press can take bits of up to 1/2 shank size and many of those are drill bits up to an inch wide. ( it's quite common to have large drills with reduced shanks) -Other items like large hole saws can be used, as well as 'fly cutters', which are cutting bits on the end of a movable beam. These can usually cut holes in thin materials like plexiglass sheet, up to a foot in diameter. Forstner bits up to 6 or 8 inch can be used, these cut large, flat bottomed holes for installing clocks and other instruments. Milling bits can be used to 'mill' large areas of rough surface to smoothness, and 'square hole tools' can also be used. The large drill press is a very versatile tool.

What is the most effective pulley?

Oh, dude, the most effective pulley is the compound pulley system. It's like the rock star of pulleys, combining fixed and movable pulleys to give you some serious mechanical advantage. So, if you're looking to lift heavy stuff with minimal effort, that's the one you wanna go for.


How is the design of a fixed pulley different from the design of a movable pulley?

A fixed pulley is stationary and changes the direction of force, while a movable pulley moves with the load and provides a mechanical advantage by distributing the force over multiple ropes. Fixed pulleys have a single attachment point, while movable pulleys have two attachment points—one fixed and one moving.


Is an elevator a fixed pulley or a movable pulley?

An elevator typically uses a combination of fixed and movable pulleys. The pulley at the top of the elevator shaft is fixed, while the pulleys attached to the elevator cab are movable. This setup allows for the efficient movement of the elevator cab up and down the shaft.


What is a single moveable pulley?

A simple single pulley enables the applied force to change direction. A pulley at the top of a well is the common example. In many applications, such as the fan belt on a car, it is used to transfer energy from one shaft to another.


What are two kinds of pulleys?

A fixed pulley and a movable pulley Block and tackle is made up of both


What is the advantage of a movable pulley?

a fixed pulley changes the direction you are executing the force in. fixed pulleys are made to work with gravity which makes the work you must use less than if you were lifting straight up and against gravity.


A single fixed pulley changes the direction of the?

single fixed pulley changes the direction of the applied force, you pull down, the object goes up.


What is moveable pulley?

A fixed pulley is a pulley that is attached to a structure and does not move;changes the direction of the effort force used to life a load by a person or a spring scale and if you use a spring scale then you will need a person to pull the spring scale done to see how far she/he pull it A moveable pulley is a pulley that supports the load and is not fixed in place;reduces the amount of effort force needed to pull to lift the load when she/he pulls the spring scale then it will tell she/he pulls it.


A movable pulley reduces the amount of effort needed to lift a lode by making what change?

A movable pulley reduces the effort needed to lift a load by changing the direction of the force required to lift the load. By pulling down on one end of the pulley system, the load is lifted up with less force needed due to the mechanical advantage gained from the pulley's design.


How does a movable pulley make work easier?

A fixed pulley is the only pulley that when used individually, uses more effort than the load to lift the load from the ground. The fixed pulley when attached to an unmovable object e.g. a ceiling or wall, acts as a first class lever with the fulcrum being located at the axis but with a minor change, the bar becomes a rope. The advantage of the fixed pulley is that you do not have to pull or push the pulley up and down. The disadvantage is that you have to apply more effort than the load


What pulleys are there?

Gears Are Relevant To Pulleys Because Gears Turn Into Circles So Do Pulleys The Difference Between A Gear And A Pulley Is... A Pulley : Pulley Has Strings To Hold On One Goes Up And The Other One Across A Gear : A Gear Has No Strings To Hold On Woozworld/Weeworld Try These Games There AWESOME!


Is a well a fixed movable or compound pulley?

A well is not a pulley at all. It is a structure dug or drilled into the ground to access groundwater. It is used to draw water up using methods such as buckets or pumps.
