What does the pulley do?
The pulley is like a wheel with a string going on one side going up and around then down the other side. When you pull one side it lifts the load that is on the other side rises and when you let go the load dropps. PEACE OUT! ={)
How is a pulley useful?
I think a pulley is useful because it can help you and other people to.
What force is overcome when a pulley is used?
A simple pulley is a rope (or chain or belt) with one wheel this may be a class 1 or class 2 pulley.For a class 1 pulley, the pulley stationary and the force applied to the rope is in the opposite direction as the movement of the object.For a class 2 pulley, the pulley is attached to the moving object and the force applied to the rope is in the same direction as the motion of the object.A compound pulley, consisting of an arrangement of more than one simple pulley, provides many other possibilities with the direction of force either the same direction or the opposite direction of the motion of the object being moved.
What is a 1st class pulley?
A fixed pulley with a rope passing through the pulley. The load is attached to one end and a force is applied to the other end.
What are the differences between a fixed pulley and a moving pulley and how do each of them change work?
The difference between a fixed pulley and a movable pulley is, the wheel of a fixed pulley does not move because the wheel is attached to a wall, ceiling, or other object. Unlike a fixed pulley, a movable pulley's wheel does move. The wheel on a movable pulley is not attached to a wall or other object. A fixed pulley changes work by changing the direction of a force. A movable pulley changes work by reducing the input force needed to lift heavy objects. A movable pulley changes the direction of the input force and reduced it. A movable pulley also increases the output force.
How do you restring the pull cord of a Briggs and stratton tiller?
Remove the cover of the engine which has the pullstarter in it, Clean it well before starting, Looking at the underside - there are three bent over metal tabs, and a pulley, Remove the leftover string noting where the knot sat and where the hole is, WITHOUT removing the pulley, unbend the tabs that are holding the pulley in, Keep a hand on the pulley AT ALL TIMES, as if it comes out so will the spring, Tie a knot in the end of the new string, and feed the other end into the hole in the pulley, and out the hole in the housing, Put the starter handle on the end of the string and tie a big knot, You shoud now have the string fitted, ready for tensioning, To tension, pick the string out between the pulley and the housing, near where the little notch is in the pulley, so you can grab the string and pull some out like a loop, Then grabing the string, which is in the notch and now has some slack, turn the pulley and string together, in the direction (usually anticlockwise) it turns when your pulling the starter handle, go around a few times, then while still holing the pulley in - pull the string by the starter handle to suck in the slack, Repeat this until required spring tension reached, Bend over at least on tab to keep the pulley in the housing.

How are a circumference and diameter related what is the difference between the two?
The circumference is diameter times Pi (3.14159). The circumference is the distance around the outside of a circle (think of the edge of a plate) and diameter is the distance across the center of the circle, like a string stretched from one side to the other.
What is a kite string attached to?
Kite string comes on wooden dowels, about half an inch to an inch in diameter, with the string wrapped around the dowel. One end of the string is attached to the kite, while the other end is attached to the dowel that you hold while flying the kite. The dowel allows you to easily release more string to let the kite go higher, or to reel the kite back in to you.

Are water pumps off a 1998 an 1994 dodge ram 1500 the same?
The 1994 would have a bolt on pulley while the 1998 had a pressed on pulley. Other than that they are same. A new pump would be of the pressed on pulley style.The 1994 would have a bolt on pulley while the 1998 had a pressed on pulley. Other than that they are same.

How does a tin can telephone work?
Required: Two tin cans, a length of string. A small hole is made in the bottom of each can large enough for the string diameter. The string is pushed through the hole in bottom of each can and a large knot tied to prevent it from pulling back through the hole. when the string is kept taught between the cans, it is possible to transmit and receive sounds from one can to the other via the taught string. The string acts as a mechanical sound conductor. Increased efficiency can be achieved by substituting suitable wire for the string. Of course if you want to cheat - just use your I-phone!
