How is the friction force produced​

Physics

Explanation:

Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.

Friction is the resistance of motion. Which means when resistance applies it makes friction which makes friction force.

A pendulum of length L is suspended from the ceiling of an elevator. When the elevator is at rest the period of the pendulum is
Stolb23 [73]
<h2>Option A is the correct answer.</h2>

Explanation:

When an elevator moves upward with consonant acceleration a, the overall acceleration on the body is given by

                        a' = a + g

So acceleration of pendulum is a + g.

We have equation for period of simple pendulum

                     T=2\pi \sqrt{\frac{l}{a'}}

In normal case a' = g here a' is more.

From the equation we can see that period of simple pendulum is inversely proportional to square root of acceleration.

Since acceleration increases period decreases.

Option A is the correct answer.

You place a box weighing 268.3 N on an inclined plane that makes a 42◦ angle with the horizontal.
vivado [14]

Answer:

Wy = - 268.3*cos(42) = - 199.38 [N]

Wx = 268.3*sin(42) = 179.52 [N]

Explanation:

To solve this problem we must make a free body diagram, in the attached image we can see a free body diagram.

Taking the inclined X & y axes with the same angle of 42°, we can see that the weight can be decomposed on both axes.

Since the angle is adjacent to the y-axis, we can use the cosine function

Wy = - 268.3*cos(42) = - 199.38 [N]

Wx = 268.3*sin(42) = 179.52 [N]
