|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 F1) exerted onto the pin by the vertical guide and the force (call it F2) exerted onto the pin by the rotating arm.
Note : Because we neglect friction the force F1 is perpendicular to the vertical guide and the force F2 perpendicular to the length axis of the rotating arm.
In addition to the length b=1m the following are given :
