In summary, the conversation discusses the force required to move a cylinder with a diameter of 60 mm and length of 500 mm, weighing approximately 11 kg. The participants consider factors such as the type of movement (rolling or sliding), the surface material, and the presence of friction. They also mention the formula for calculating force as F=m.a, but clarify that this formula is not directly applicable to rolling resistance.

Hello


I have a cylinder that diameter is 60 mm,length is 500 mm and this is approximately 11 kg .If i want to move the cylinder,how much force do i need to move?
How i calculate this kind of cylinders?

are you rolling it? or is it sliding on it's circular face? what material is it being pushed on?
 
  • #3
yes,it is being rolled and if u want to learn about friction value,it doesn't matter.
 
  • #4
well, if no friction, and perfectly flat surface, I don't think you need very much force at all. it's so precariously balanced on a hard line, that it should fall forward (roll) at the slightest push.

rolling resistance is your weight (lbs or Newtons(kgs*9.81)) multiplied by your rolling resistance coeff. If no rolling resistance coefficient than no force to overcome that roll.

Thanx huntoon :), you say that we use this formula ( F=m.a) .
 
  • #6
I didn't say that. I said the force you need to roll something is it's weight * its rolling resistance coeff.
 

FAQ: Calculating force we need to turn

What is the formula for calculating force needed to turn an object?

The formula for calculating force needed to turn an object is force = mass x acceleration, where mass is measured in kilograms (kg) and acceleration is measured in meters per second squared (m/s^2).

How do you determine the direction of the force needed to turn an object?

The direction of the force needed to turn an object is determined by the direction in which the object is being turned. For example, if the object is being turned clockwise, the force needed will be in a clockwise direction.

What factors affect the force needed to turn an object?

The force needed to turn an object is affected by the object's mass, the speed at which it is turning, and any external forces acting on the object (such as friction or air resistance).

How can you decrease the force needed to turn an object?

You can decrease the force needed to turn an object by decreasing its mass, decreasing its speed, or reducing any external forces acting on the object. For example, using lubrication can reduce friction and make it easier to turn an object.

What units are used to measure force?

The standard unit for force is the Newton (N), which is equivalent to 1 kilogram meter per second squared (kg m/s^2). Other common units for force include pounds (lb) and dynes (dyn).
