The normal method of loading provisions is with a deck crane and cargo nets however in this instance the crane is under repair. It has been agreed to use a simple method of a hoist to drag the provisions on board using a smooth gangplank and the load secured to wooden skids. The incline of the gangplank is (21) and (13) metres long, the coefficient of limiting friction of wooden skids on a smooth wood surface, u is 0.3, the total mass of the provision and wooden skids (0.9) tonnes per lift, the maximum velocity from rest is (3.6) m/s, takes g = 9.81 m/s. Calculate using d'Alemberts Principle: a) What force will be applied? b) The maximum power developed, and c) Produce a neat free-body diagram to show your understanding. I
