Hi, attempted the question, but my answer is incorrect
and I don't know why. I have broken down my solution into steps so
that you could hopefully more easily help me identify my mistake/s.
I need help with understanding the question and what it is I do and
don't understand more than just the answer.
Thank you :)
(A) Angular velocity of BC:
(B) Acceleration of B:
(C) Using values from step (A) and (B) to obtain
expression for the acceleration of C:
The angular acceleration of BC is still unknown, so must find another equation.
(D) Velocity of C and then angular velocity of
(E) Using angular velocity from step (D) to obtain
ANOTHER expression for the acceleration of C:
(F) Equate expressions for the acceleration of C from
steps (C) and (E) to find unknowns and finally calculate the value
of the acceleration
