to BD, and AC is vertical.
(b) Determine the reactions at A and B. 2. (12 marks) The sketch shows a shaft BF with
levers at both ends , act ed on by a force P = 500N at
E and a force Q at A. The shaft is supported by
frictionless bearings at C and D which are aligned
with the shaft. Bearing D can exert an axial thrust,
but bearing C can not. Lever AB and force P are
parallel to the x axis, while lever FE and force Q is
parallel to the y axis. Calculate the force Q and the
components of the reactions at C and D, assuming
