This lesson explains what is mechanical advantage and how to find mechanical advantage. Mechanical advantage formulae are provided for various machines. Related to this Question Name the pulley which has no gain in mechanical advantage. Explain why such a pulley is used....
A pulley is a type of simple machine which has a wheel on an axle designed to support movement, change the direction of the cable, and transfer power between the cable and the shaft. There are three types of pulleys - fixed, movable and compound pulleys. A fixed pulley is a...
The lathe can swing a pulley of 12 inches diameter. Swing To put (a door, gate, etc.) on hinges so that it can swing or turn. Swing (nautical) To turn round by action of wind or tide when at anchor. A ship swings with the tide. Swing The manner in which something is swung. ...
Traction elevators use steel ropes pulled along a deeply grooved pulley. Hydraulic elevators use a piston to push the elevator up from below. Both types require counter-weighting, which is typically accomplished by the placement of another elevator car on the other end of the ropes. Hydraulic ...
It is seen in the gentle motion of standing structures or people trying to maintain equilibrium. Swing, however, involves a wider range of motion and is linked to activities that require momentum, such as playing on a swing set or hitting a golf ball. 6 Sway is sometimes used in the ...
What type of elevator is used for high rise buildings? Traction Elevators This type of elevator is more popular with mid and high-rise buildings. They have a faster speed in comparison with hydraulic lifts, meaning that they can take you from point A to point B fin a shorter amount of ti...
It is the portrait of a straight-speaking, dedicated rock climber with incredible mental control who managed to do what was previously thought impossible. He climbed El Capitan without safety ropes, putting himself intentionally into a “you slip, you die” situation that goes on for one tenuous...

Early learners in physics have a tendency to look at stationary objects and deduce that no forces are be applied. In objects not undergoing acceleration however (whether moving or stationary) are in a state of balanced forces. In a book sitting on a table for ...
