In forging pressure P and longitudinal stress (σx
) build up to a maximum value at the centre
of the plate(work), and reduce to a minimum value at the edge(end) of the plate. When this
variation in P & ( σx
) is plotted over the entire length, a peak exists at the centre,
resembling a "hill".
This plot is called as friction hill.

In what way is friction useful to a skydiver?
Friction (from air resistance) stops them from falling faster and faster continually - instead they reach a maximum velocity and stay at that speed until they pull their parachute. Friction prevents them from plummeting to their death.
What are advantages of wheel?
Rolling friction is less than sliding friction so it is easier to move heavier objects using wheels.
When you stand on a slope why don't you slide?
That depends on the friction, or grip, between your feet and the surface you are standing on. Its a battle between gravity and friction. If you are in bare feet on ice, mud, or wet grass or clay, gravity wins and you take a tumble. If you are wearing hiking boots on rock, stone, or any surface with a little friction, friction wins.
What contributions did charlotte angas Scott do for mathematics?
Charlotte Angas Scott was a revolutionary forging through various obstacles to acquire numerous firsts for women in the field of mathematics.
What is the unit measure of friction?
As friction is also just a type of force (an oppsoing force), it's standard unit is also Newton as of any other force.
How the law of friction affects down hill skiing?
if there is friction on the hill it will slow you down
Is the friction of the wagon moving down the hill static?
No, the friction of a wagon moving down a hill is typically kinetic friction. Static friction occurs when an object is at rest and there is no motion relative to the surface.
Is a bicycle rolling down a hill friction?
Yes, as the bicycle rolls down the hill, there is still some friction present between the wheels and the surface of the hill. This friction helps to slow down the bicycle's descent and eventually bring it to a stop.
What is the force stopping from rolling down a hill?
The force stopping an object from rolling down a hill is friction. Friction occurs between the object and the surface of the hill, creating a resistance that opposes the object's motion. It is this frictional force that prevents the object from sliding or rolling down the hill uncontrollably.
The friction involved in a wagon moving down a hill is?
The friction involved in a wagon moving down a hill is mainly kinetic friction between the wheels and the ground. This friction slows down the wagon and prevents it from accelerating uncontrollably. It is affected by factors such as the weight of the wagon, the angle of the hill, and the condition of the wheels and the surface.
Does a ball rolling down a hill cause static friction?
No, static friction is the resistance that prevents an object from moving when it is not in motion. As the ball is already rolling down the hill, it experiences kinetic friction (dynamic friction) between the ball and the surface of the hill.
Do you use friction when you ski down a hill?
yes. there is friction to resist every movement we make
What is impress-die forging?
Impression forging is die forging. please see the introduction from SK forging Group,If you need more info, you may visit their website on the following. www.forgingmanufacturer.comDie forging is the most widely used forging process in today's forging industry. As a large forging manufacturer in China, SK forging group has the unique advantages on die forging technology. SK Forging has 23 die forging production lines. Die forging is usually divided into open die forging and closed die forging. The size of die forgings of SK is from 50mm to 2000mm, weight is from 0.5Kg-200Kg. What is die forging? Die forging is a forging process that forging metal in plastic deformation under external force and be full of forging mold. Die forging can be divided into open die forging and closed die forging. Compared with the free forging, die forging must need a mold to forge. The mold of forging determines the size, shape and quality of products. Therefore, the mold is a very important part in die forging process. Die forging equipmentsThe equipments commonly used in die forging are die forging hammer, hot forging press, flat forging press, friction forging press and others. Features of die forging:1. Compared with the free forging, die forgings have precision size, less machining and a more reasonable distribution of fibrous tissue. All these advantages may enhance the service life of forging parts.2. Die forging with high productivity, simple operation, easy to implement mechanization and automation.3. However, die forging need much investment in equipments and long production preparation. The quality of die forging parts was restricted by the equipment press. Die forging usually applied to small and medium-sized forgings (usually
When is friction necessary for some type of movement to occur?
If a ball slides down a frictionless hill there will be no rotation of the ball. But with friction the ball will both translate and rotate down the hill.
What force allows you to walk up a hill withuot sliding back down?
Friction is the force that allows you to walk up a hill without sliding back down. The friction between your feet and the surface of the hill provides the necessary grip to overcome gravity and maintain your position.
What slow down an object when it rolls down a hill?
friction
When a car is going down a hill covered in ice what friction would that be?
unless you have chains or studs it would be 0 friction
