This happens because the pulley is already holding up some of the weight. The object that is in the rope is supported for some of the weight because of the pulley. If you had something about 20 pounds connected to a pulley, the pulley already takes off some pounds. You may be pulling 20 pounds but it feels like, say 15 pounds because the pulley supports 5 pounds already.
What else can I help you with?
What kind of pulley changes the direction of input force but does not change amount of force you apply?
A single pulley alters the direction of the input but confers no mechanical advantage.
What type of pulley changes the direction of the input force but does not change the amount of force you apply?
A fixed pulley changes the direction of the input force without changing the amount of force applied. It is attached to a fixed point and does not move, simply redirecting the force in a different direction.
What kind of pulley changes the direction of the input force but does not change the amount of the force you apply?
They pulley is applied by the output force and then it is being added on by the input work.
How can pulley be use to change direction?
A pulley can change the direction of a force by redirecting the force applied to it. By wrapping a rope around a pulley and applying a force in one direction, the pulley can change the direction of that force to lift an object in a different direction. This enables easier lifting or lowering of objects in a variety of applications.
What does a pulley do to the direction of a force?
Pulleys change the direction of a force.
Which type of machine change the direction or amount of force needed to do work?
Simple
How pulley help?
can change a direction of a force
A pulley system can?
Change the direction of force and multiply the force.
Which pulley is used to changed the direction of the force?
A changing the direction of force is generally achieved using a fixed pulley or a movable pulley, depending on the specific setup. Both types can redirect the force being applied to a different direction without changing the amount of force.
What is the job of the single pulley?
A single pulley is used to change the direction of a force applied to a object or to increase the force applied to move the object. It reduces the amount of force needed to lift heavy objects by distributing the weight across multiple ropes or chains.
What does a fixed pulley change of a force?
A fixed pulley does not change the amount of force required to lift an object. However, it changes the direction of the force applied, making it easier to lift objects by allowing you to pull downward instead of upward.
What kind of pulley changes the direction of the input force but does not change the amount of force you apply?
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 is 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.
