Question about torque and friction

In summary, the conversation discusses the reason why a box does not slide when pushed on top of it, but rather lifts on one corner. The suggested explanation is that there is friction on the surface, preventing the box from sliding. To tip the box, there needs to be a net torque, rather than a net force. The conversation also suggests drawing a free body diagram and writing equations related to torque.

Homework Statement


We have a box has W as widht and h as height.Now when we push it on top of it, it does not slide but the side is closest to us is lifting. We consider center of the mass in center.

Homework Equations

The Attempt at a Solution


I think the reason of lifting just one corner is because of friction on the surface and It is not sliding because our torque does not reach maximum value of static friction but I can not write an equation how much force needed to tip it

Are you asking why the box will tip and not slide? Remember for the box to slide it needs net force and to tip it needs net torque. Try writing the force and torque equations.

1. What is torque?

Torque is a measure of the turning or twisting force of an object. It is calculated by multiplying the force applied to an object by the distance from the point of rotation to the point where the force is applied.

2. How is torque different from force?

Force is a push or pull on an object, while torque is a rotational force. Force is a vector quantity, meaning it has both magnitude and direction, while torque is a vector quantity that also takes into account the distance from the point of rotation.

3. What is the relationship between torque and friction?

Friction is the force that opposes motion between two surfaces in contact. Torque can be affected by friction, as friction can create a resistance to the rotational force applied to an object.

4. How does friction affect an object's torque?

Friction can reduce the effectiveness of an object's torque by creating a counterforce that opposes the rotational force. This can cause the object to rotate slower or not at all.

5. How can friction be minimized to maximize an object's torque?

To minimize friction and maximize an object's torque, lubricants can be used to reduce the contact between surfaces and decrease the resistance to rotation. Additionally, using smoother and more evenly distributed surfaces can also reduce friction and increase torque.
