PROBLEMS The hydraulic cylinder AB exerts a force F of constant
magnitude 2.5 kN directed from A to B as the engine is
elevated. Determine the moment of F about the point C as a
function of q for the range 0≤ q ≤90o.
What is the weight W of the
engine if the combined moment
about C of the force F and
weight W for q =30o is equal to
zero?

PROBLEMS Rectangular plate
ADCF is held in
equilibrium by string
AB which has a tension
of T=14 kN.
Determine,
a) The magnitude of
the moment of about
the axis DC,
b) The perpendicular
distance between lines
AB and DC.
