Question

Assume that F1 = 48 N , F2 = 44 N , and F3 = 96 N

A.) In object A indicated in the figure, what magnitude of force F is needed to put the object into rotational equilibrium about the axis A shown?

B.) In object B indicated in the figure, what magnitude of force F is needed to put the object into rotational equilibrium about the axis A shown?

C.) In object C indicated in the figure, what magnitude of force F (if any) is needed to put the object into rotational equilibrium about the axis A shown?

D.) In object D indicated in the figure, what magnitude of force F (if any) is needed to put the object into rotational equilibrium about the axis A shown?

E.) In object E indicated in the figure, what magnitude of force F (if any) is needed to put the object into rotational equilibrium about the axis A shown?

F.) After you have found the F required to put the object into rotational equilibrium, find out which (if any) of these objects is also in translational equilibrium.

Enter your answer separeted with commas or enter none, if there are no object in translational equilibrium.

Explanation / Answer

Rotational equilibrium

Tnet= 0

A.

-30*F1 + 10*F=0 ; -30*48+10*F =0

F= 144 N

B.

-10*F1+30*F =0 ; -10*48+30*F=0

F= 16 N

C.

-30*F1-20*F2+10*F=0 ; -30*48-20*44+10*F=0

F=232 N

D.

-10*F1+30*F=0 ; -10*48+30*F=0

F=16 N

E.

30*F1-15*F3+10*F=0 ; 30*48-15*96+10*F=0

F=0 N

F.

None.
