Problem # p042 |

The pin A of mass m=0.8 kg slides inside the slot of the vertical guide
CD as the arm 0B rotates around the fixed point 0. Neclect friction and gravity in order to calculate the force (call it F _{1}) exerted onto the pin by the vertical guide and the force
(call it F_{2}) exerted onto the pin by the rotating arm. Note : Because we neglect friction the force F _{1} is perpendicular
to the vertical guide and the force F_{2} perpendicular to
the length axis of the rotating arm.In addition to the length b=1m the following are given : |

- Give the value for the x-component of the velocity of the pin.
- Give the value for the x-component of the acceleration of the pin.
- Find the equation for the y-location of the pin as function of the distance "b" and the angle Θ.
- Determine the equation for the y-component of the acceleration of the pin and determine its value for the Θ etc.
- Use F=ma in the x- and in the y-direction to determine the values
for F
_{1}and F_{2}.
