### Why do 2 points on a mechanism not have the same angular velocities?

The velocity of P' is perpendicular to AD, and the velocity of P is perpendicular to BP. So clearly the directions are not the same. Thus there is relative velocity between P and P' as shown in the ...

### Would a car slip down on a frictionless banked road and situation for friction road

Frictionless surface. Assuming the initial velocity is perfectly tangential to the circular motion to begin with : greater than $u_0 >\sqrt{g R \sin\theta}$, then the car will spiral outwards less ...

### Frictional wheels without slipping (gear system)

The concept behind the friction force should always be greater than the tangential force is that the maximum friction force should be greater to the force that causes the rotation of the wheel. If ...

### Radial and transverse velocity

You could calculate the velocity magnitude from total energy (gravitational and kinetic) of the comet, which must be constant: E = E_p+E_k = -\frac{G\cdot M\cdot m}{r_A}+\frac{1}{2}m\cdot v_A^2 = -\...

### What is meant by "shock load" in gears?

In gear design for different machinery there is a combination of loads that causes damage and excessive wear and the equation for that load: F* = Ka Kv Km Ft Ka is application factor inherent ...
