A pulley is a surface that redirects force using a rope. By changing the direction of the force applied to the rope, pulleys can help in lifting heavy objects or changing the direction of a force.
A pulley.
Pulley.
the force of tension in the rope, which is delivered to the object to which the opposite end of the rope is attached
50 kg (on Earth) weighs about 110 pounds. If you're using a simple, singlepulley with a rope passing over it, then that's the pull you need on the rope tolift the bundle of shingles. If you're using a block and tackle arrangement ofmultiple pulleys, then you'll get away with much less pulling force on the rope,but you'll have to pull the rope much farther.
A pulling force in a rope is called tension. Tension is the force exerted by a rope when it is pulled taut by two opposing forces.
That depends on the specific situation. Note that by Newton's Third Law, the force exerted by a wall on a rope is the same as the force exerted by the rope on the wall.
i have a great scince teacher and she said it means a levers i hope it helped you prove or do your homework
I am not sure what you mean by "a surface that re-directs force" but you could use a pulley to redirect a force from a rope.
Is a pulley
Pulley.
A rope winds around the pulley so that two ropes hang downwards. Using one side of the rope to apply force causes the pulley to rotate and redirect the force, moving the load upwards even though the pull is applied downwards.
A block of mass M is pulled with a rope on a frictionless surface If a force P is applied at the free end of the rope what will be the force exerted by the rope on the block if the mass of rope is m? Equation#1: Force = mass * acceleration The force P pulls a total mass of (M + m) accelerating both masses at the same rate. Equation #2: P = (M + m) * a Equation #3: a = P ÷ (M + m) At the point where the rope is attached to the block, the block of mass M feels a force making it accelerate at a rate of a = P ÷ (M + m). The force required to make at block of mass M accelerate at a rate of a = P ÷ (M + m) can be determined by equation #4. Equation #4: F of block = mass of block * [P ÷ (M + m)].

A sheave wheel, also known as a pulley, is a simple machine with a grooved wheel that a rope or cable runs through. Its main function is to change the direction of the force applied to the rope or cable. When you pull on one side of the rope, the sheave wheel redirects that force to another direction, making it easier to lift or move heavy objects. Sheave wheels are commonly used in various applications, from lifting weights in construction to operating machinery like elevators and cranes.
That depends on the specific situation. Note that by Newton's Third Law, the force exerted by a wall on a rope is the same as the force exerted by the rope on the wall.
Tension is the force that occurs in a rope when both ends are pulled in opposite directions. This force acts to stretch and elongate the rope.
