Simple
Simple machines that rely on changes in direction to make work easier include **pulleys** and **levers**. A **pulley** changes the direction of the force, allowing you to lift objects more easily. A **lever** can change the direction of the input force depending on where the fulcrum is placed. visit our website: www. trustlandindia .com/property-type/construction-site/
A machine makes work easier by changing at least one of three factors. A machine may change the amount of force you exert, the distance over which you exert your force, or direction in which you exert your force.
1. change the size of the force (eg. lots of cranking of car jack to lift car small amount). 2. change the speed 3. change direction of force (simple pulley - force one way, resistance moves in other direction)
To make an object change direction, you can apply a force in the opposite direction to its current motion. This force can be applied using mechanisms like a motor, thrusters, or steering mechanisms depending on the type of object. By adjusting the magnitude and direction of the force applied, you can control the object's change in direction.
To make an object move, a force is required. To change the direction of an object's motion, a different force must be applied in the desired direction. To stop the motion of an object, a force opposite to its direction of motion, known as a braking force, can be applied.
Machines make work easier by: -Changing the amount of force you exert -Changing the distance in which you exert your force -Changing the direction in which you exert your force
Simple machines can increase force by allowing a person to exert their force over a longer distance, reducing the amount of force needed. They can also change the direction of the force applied, allowing for easier movement or lifting of objects in a different direction than the force applied. Overall, simple machines help make work easier by trading off force and distance in a way that benefits the user.
by changing the direction of the force you applied
They make communication easier. They give people health and they make jobs easier.
a device that helps make work easier by changing the size or direction of force
A machine that changes only the direction of force has a mechanical advantage of 1. This is because it does not multiply the input force, but rather changes its direction to make work easier.
