presentative Problems

Link $AB$ rotates through a limited range of the an$-$

gle $,$ and its end A causes the slotted link $AC$ to

rotate also. For the instant represented where $=$

$60$ and $=0\mathrm{.}6ra\frac{d}{s}$ constant, determine the cor$-$

responding values of $r^{},r^{},{}^{},$ and ${}^{}.$ Make use of Eqs.

$\frac{2}{13}$ and $\frac{2}{14}.$

Ans. $r^{}=77\mathrm{.}9m\frac{m}{s},r^{}=-13\mathrm{.}5m\frac{m}{s^2}$

${}^{}=-0\mathrm{.}3ra\frac{d}{s},{}^{}=0$
