Question : 40 of 65

Marks: +1, -0

The crank of a slider-crank mechanism rotates counter-clockwise (CCW) with a constant angular velocity

ω

, as shown. Assume the length of the crank to be

r

Using exact analysis, the acceleration of the slider in the

y

-direction, at the instant shown, where the crank is parallel to

x

-axis, is given by

Solution:

Velocity of point

{A}, V_{A}=r × ω

.
The radial acceleration of point

{A}, a_{o a}=r ω^{2}

Since, the inclination of line

A B

is 45 degree, the acceleration of the point B will be equal to the acceleration of point A. i.e.

r ω^{2}
