The robot arm is elevating and extending simultaneously. At a given instant, $=40,{}^{}=45de\frac{g}{s},{}^{}=132de\frac{g}{s^2},l=0\mathrm{.}37m$

$l^{}=0\mathrm{.}32\frac{m}{s},$ and $l^{}=-0\mathrm{.}34\frac{m}{s^2}.$ Compute the radial and transverse forces $F_r$ and $F_{}$ that the arm must exert on the gripped part $P,$

which has a mass of $m=15\mathrm{.}8kg.$ Compare with the case of static equilibrium in the same position.

Assume $d=0\mathrm{.}89m$
