A paradox while explaining the equilibrium of books
An even number of books (say four) are held in the manner shown in the figure. It is obvious that if we apply a large force inwards, we can increase the normal force, and hence the friction which ...

The application of a minimum and maximum force
There are three blocks - a big block (C) above a horizontal surface that is smooth. A block (A) of mass m is resting on block C, and is also connected to another block (B) of mass m through an ideal ...

A case of limiting equilibrium
I have noticed in the solutions of the problems of Friction of a physics book I'm studying from that in cases of limiting equilibrium, the force of friction $f$ to be equal to the coefficient of ...

Need help with a physics question about a ladder leaning against a wall [closed]
I am struggling with a physics question that involves a ladder leaning against a wall. I have attempted to solve the problem, but I am not confident in my answer.
The question is as follows:
"A ...

Confusion with the concept of stable equilibrium of pendulum at resting position
According to my understanding, an oscillating pendulum is not at equilibrium, since its momentum and velocity changes with time. Now my question is that we say that the pendulum at its resting ...

Problem with possibly infinite possible solutions [closed]
Problem figure:
In the problem, the string is light, inextensible and initially, before the application of the external forces, the string is just taut with no tension and the blocks were at rest. ...

Will static friction be zero unless it's necessary for maintaining equilibrium? [closed]
While solving a problem related to equilibrium, I assumed that friction would be zero (I wasn't sure if it was correct) unless friction was required to maintain the system in equilibrium. This got me ...

How should I produce an equation for coefficient of static friction in the vertical axis?
I am currently working on the observation of the relationship between the weight of blocks and the inward force required to sustain the row of blocks. This is similar to the other posts from this site ...

How to make an object at rest in a frictionless surface move at constant velocity?
let's imagine an object at rest in a frictionless surface (ignore air resistance too!) how can we make it move at a constant velocity?
we need force right? If force is applied wouldn't it accelerate ...

Horizontal Rack of blocks revisited a.k.a. if it were on top of lava, which block would you choose to stand on?
This question is a follow up to the following question asked by esdoublelef
Free body diagram on a rack of wooden blocks
To repeat, consider a rack of blocks (each block is a cube), that are held up ...

Is it possible that the tension force would arrive before friction in this problem?
A rigid block is tied to a practically inextensible string with no slack to a wall. The max value of static friction is 10N. An external force of 12N is applied to the block pulling it away from the ...

Direction of static friction in rolling without slipping down an inclined plane
Suppose a wheel is rolling without slipping down an incline. Static friction prevents the impending motion of the wheel relative to the incline. Since the slip is impending in the direction in which ...

Statics Question about Friction on an Incline
So for an object, say a block, on an incline, there hold three cases in which minimum force $P$ is dependent:
a.) To start the block moving upwards.This is the case where static friction is at the ...

Will friction on tyres due to road still act if the vehicle is moving with constant velocity?
A car moves with the help of friction from ground...while analyzing a car moving with constant velocity..should one consider the frictional force acting at the contact point of road and wheel?
