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?
