Homework H$\mathrm{.}3.$D

Given: A guide rod is able to control the angular position of the L$-$shaped arm BOE through its

end A moving vertically and through the slot cut into section OE of the arm. In turn, arm BOE

controls the horizontal position of slider C through end B being constrained to move within the

slot in slider C$.$ For a particular task of this mechanism, end A of the guide rod is moving upward

with a constant speed $v_A.$ Our goal is to determine the velocity and acceleration of slider C $.$

Find: For this problem:

$($a$)$ Determine the angular velocity and angular acceleration of arm BOE.

$($b$)$ Determine the velocity and acceleration of pin B on BOE.

$($c$)$ Determine the velocity and acceleration of slider C$.$

HINT: Consider using an observer attached to the slotted arm BOE.

Use the following parameters in your analysis: $v_A=20f\frac{t}{s},=30,L=2ft$ and $d=1\mathrm{.}5ft.$
