What effect does the friction coefficient have on belt drive
Premise: the static friction force is greater than the component force of the gravity of the object along the conveyor belt direction f = UN, the greater the friction coefficient u is, the greater the F is. When the conveyor belt is just put on, the relative displacement between the object and the conveyor belt is determined by Newton's second law f = Maun = man = mgsin ϴ Get a = ugsin ϴ From V2 = 2As, V2 = 2ugsin ϴ S is: S = V2 / 2ug
Hope professionals to answer. Friction, contact area, volume, friction coefficient, pressure. The role of several factors From junior high school logistics, we have learned the formula of friction. We know that the size of friction has nothing to do with the contact area, but depends on the size of pressure and friction coefficient. But we watched a video about why geckos can walk on the wall. It is through the fluff on their claws that the contact area is increased. I have a question, why geckos increase through the contact area, Can increase the force. I do auto parts and brake pads. I have questions about this. Will brake pads produce different braking forces under the same material, the same pressure and different contact areas? Ask professionals for answers. Or do I take into account the friction force and do not take into account the simultaneous action of different forces. The formula of friction force, It should be realized in absolute state. Is there no ideal form in the real world, and the contact area and friction area are two concepts? I'm confused. I don't know if my expression is clear
Your understanding is incorrect. Geckos don't walk on the wall by friction. Even vertical wall geckos with friction coefficient of 0 can walk
Gecko's fingers and toes expand, forming skin folds under them, densely covered with glandular hairs, with adhesion ability. After sticking, it gives him power. The upward force is tensile force, just like a small hook hanging on the wall. In fact, the smooth wall is uneven after magnification. If it's hard to understand, imagine climbing the mountain to fix the nail on the wall and drag it upward, not the power provided by friction
Is the magnitude of friction related to the contact area?
Don't mislead, the magnitude of friction F= υ Fn υ Is the friction coefficient FN is the pressure
So it doesn't matter
It is known that the vehicle weight is 35 tons, the friction coefficient is 0.15, and the slope is 15 degrees. Is there a formula for calculating the gravitational acceleration
Friction f = mg * cos15 * u (friction coefficient); Gravity g = mg * sin15. If uphill acceleration a = (F + G) / m. if downhill acceleration a = (G-F) / m
How to find the formula of slope friction without considering what friction coefficient
As long as the object remains stationary, the friction force is balanced with the component of gravity along the inclined plane. F = Mg (sin θ）
Is friction related to the magnitude of pressure and how to use the formula,
As long as the contact surface is not smooth, the positive pressure is directly proportional to the friction. Here is the positive pressure, which refers to the resultant force in the vertical direction of the contact surface. Friction = friction coefficient * positive pressure,
Friction coefficient is the ratio of friction force to positive pressure. It is a proportional coefficient. The unit is one. You can also understand it as no unit
