The 20-lb link AB is pinned to a moving frame at A
and held in a vertical position by means of a string BC which
can support a maximum tension of 10 lb. Determine the
maximum acceleration of the frame without breaking the
string. What are the corresponding components of reaction
at the pin A? T 3 ft 4 ft A B -3 ft + C a

T 3 ft 4 ft A B -3 ft + C a
