Question

Define angular velocity ratio theorem and formula for finding between 2 links

Answer 1

Explanation:

The car's angular velocity is pi / 2 radians per minute. To get our second formula for angular velocity, we recognize that theta is given in radians, and the definition of radian measure gives theta = s / r. ... Simplifying gives w = s / (rt), where s = arc length, r = radius, and t = time

Answer 2

Angular velocity ratio theorem:

The ratio of angular velocity of two links is inversely proportional to the ratio of distances of their common I center from their respective centers of rotation.

For link 1 and link 2 with angular velocities w1 and w2 and I center I12,

$\frac{w2}{w1}=\frac{distance\ between\ I_{12}\ and\ center\ of\ rotation\ of\ link\ 1}{distance\ between\ I_{12}\ and\ center\ of\ rotation\ of\ link\ 2}$
