Problem $6\mathrm{.}5$

The chart shown is in inch unit and scaled

$($a$)$ Locate all instant centers in the mechanism shown below.

$($b$)$ If link $2$ is turning CW at the rate of $60ra\frac{d}{s},$ determine the linear velocity of points $B$ and $C$ using instant centers.

Hint: Get the chart printed and work on the printed chart in scale.

Measure the radius of rotation in need with a scale based on a known dimension $($say $3\mathrm{.}00$ in$)$

Problem $6\mathrm{.}6$

The chart shown is in inch unit and scaled

$($a$)$ Locate all instant centers in the mechanism shown below.

$($b$)$ If the cam $($link $2)$ is turning CW at the rate of $900$ rpm $,$ determine the linear velocity of the

follower using instant centers.

Hint: Dimensions in need can be obtained using trigonometry based on the angle of $103$ and $70$

angles.
