Unformatted text preview: g. Hint: Since block B cannot move
in the y-direction, there will not be a friction force at
contact e. Assume that motion is not impending for block
(b) (2 marks) For part A above, prove that motion is not
impendin g for block B.
(c) (1 mark) If an additional force Q is now applied in the direction shown, what will happen to block
A and why? Assume that the force P which was calculated to cause impending slipping in (a) part
is still applied. Answer in words - no calculations required.
6. A bent steel bar ABC of negligible weight
is supported by two cables BE and CD and by
a frictionless ball and socket joint A. It is
loaded by force P = 5 k...
