What is the theoretical mechanical advantage of a screw that has four threads per inch and a pitch diameter of 2.25 inches?
6.3
What is mean by pitch scale in screw gauge?
Screw Pitch is defined as the axial distance between threads. One complete revolution of the screw will move it into an object the distance of the pitch. The smaller the pitch, the greater the mechanical advantage (ability to do work) achieved.
Which is the simple machine that provides the mechanical advantage of 1 the screw second class lever single fixed pulley or single movable pulley?
Single Pulley
What is slotted screw?
A screw with a slot in it.
What is an example of a lead screw?
screw
How do you get the mechanical advantage of a screw?
The mechanical advantage of a screw can be found by dividing the circumference of the screw by the pitch of the screw. In this case, the total mechanical advantage is equal to the circumference of the simple machine to which the effort force is applied divided by the pitch of the screw.
What is motor?
It converts electricial enargy into meachanical enargy
What is the formula for a screws mechanical advantage?
The mechanical advantage of a screw is given as MA = circumference / pitch. The pitch of the screw is the number of threads per centimeter. The circumference is measured at the working portion of the screw, not the head.
How does a screw help you?
A screw is an inclined plane wrapped around a shaft. The inclined plane is a simple machine that offers the user a mechanical advantage. The shaft is what transmits a torque to that advantage.
Why is a magnetized screw driver an advantage to a electrician?
An magnetized screwdriver is an advantage for an electrician because it means the screw will remain attached to the screwdriver meaning it will be easier to unscrew. Hope this helps ;)

What is the Ideal Mechanical Advantage when a screwdriver with a handle of radius 1.2 cm is used to remove a screw in the back of a computer and the screw moves out 0.20 cm on each turn?
There is no advantage whether the handle is 1.2 cm or 10 cm, the screw will still only make one revolution. The reason being is that both the screw driver and the screw become part of the whole. The only increase in the screws revolutions is if the screw driver is geared to make more than one turn of the screw.
Who has the greater IMA a screw with closely spaced threads or a screw with threads spaced farther apart?
Holding the diameter of the screw constant, closely spaced threads (fine pitch) have a higher mechanical advantage than thread which are spaced farther apart (course pitch). Mechanical advantage is the ratio of travel of the applied force to the ratio of the imparted force. Because the screw must rotate more times to insert a given depth, fine pitch has a higher mechanical advantage.
What is your opinion Of the screw as a lifting device?
Even the best screws only have a mechanical advantage of twenty percent. Therefore, the screw is not a very efficient lifting device.
A 1-cm screw with a 4-cm thread would have a mechanical advantage of?
